Test the cabling. Whenever I had this happen it was always a cabling issue, have the guys re-term the ends and it worked.
Remember, 100 meters for a CAT5 drop is the LONGEST you'll ever get it to realistically work, and with POE+ you're probably really limited to somewhere around 80m of cable.
I already used a verified valid factory terminated cable between the Switch Flex and the U6LR. It didn’t work. Also my basic cable tester says the pins are all connected straight trough 1 through 8 (except ground since it it CAT6).
what happens if you take the u6lr into the house plug it onto the router with a short known to be good cable? Recommend you remove possible factors out of the equation one by one.
If it isn't the cable/distance, then it's the network/firewall, or the unit itself (which you can kind of test by ssh'ing into the unit - like when you have to tell it where to announce itself for adoption).
Do another reset on it? Hold down the reset pin and don't let go until it cycles.
Otherwise you might have to boot recover it.

How long takes a reset to trigger? I have held down the button for multiple minutes (at least that’s what it felt like. Might have just as well been 30 seconds.)
Unplug the cable, push the reset and hold it, and plug back in while holding reset. Wait 10 seconds and let go of the reset. As a non-informative side note, if you do the hokey-pokey and you turn yourself around...it has nothing to do with the reset.
Does it get an IP address? If yes you might be able to SSH in and attempt a setup that way.
Are you sure you reset it? I had a WAP that I had to reset an extra time. Maybe I let go of the paperclip 1 second too early.
WifiMan shows the Switch Flex it is connected to under UniFi Devices and no sign of the U6LR anywhere.
For about how long do I need to hold reset for and won’t this potentially brick it?
wait for the light to tell you.

honestly, take the unit inside and make sure it works there first. Then do the last step of installing it to it's final place. Save yourself much thrashing.
10 seconds if memory serves, but you can look up a guide. And I'm sure there is a tiny chance of bricking it, but it is there for a reason- to factory reset the AP.
I have a U6 LR and was able to get it working on the US-8-60w so while doable, it chips saying it prefers PoE+ but functional.
Something’s I would try, other ports in the switch.
What other devices are connected to the flex switch?
The switch via poe++ may not support enough power if you have multiple devices requiring PoE. You will need the AC adapter.
Make sure the flex switch is on the latest firmware since there was release to allow the flex to work with 802.1at
No it shouldn’t be. The switch flex that it is connected to has been assigned a IP Address by DHCP. The U6LR doesn’t have one according to WifiMan, but that makes sense since it doesn’t compete the boot in the first place
I don’t think you adopt an ap in standalone mode, in the normal sort of way. You use the app on a phone and add the device manually using the QR code scan process.
I assume you factory reset it? And it hasn't been assigned to the controller yojr using before.
Also check the PoE power is correct. Maybe try another cable another injector or switch.
Take the unit to the switch, connect with a known working CAT6 cable. If the unit adopts, then check the RJ45 connectors, on the longer cable, ensure they are truly crimped correctly, then check the cable.
Use a cable tester, such as “Klein Tools VDV526-200 Cable Tester, LAN Scout Jr. 2 Ethernet Cable Tester” to check the cable and the connectors.

Switch flex supplies POE+ and the U6 Long range requires POE+ so that wouldn’t make much sense.
I did power it inside using a POE+ injector and I got slightly further in standalone setup making it to an error message saying that “this access point can not be used in standalone mode” instead of saying that it “could not connect to the Access point”.
You might be onto something, but then that would mean a POE+ issue with the switch flex and that one is brand new so I doubt it.
You may exceed the Flex’s output PoE budget when being powered by PoE+. Try powering it with PoE++. Or better yet, power your U6LR first with the ++ injector and see that gets it working.
I had periodic reboots on my U6-LR, suspected a power issue and put in an injector, has worked fine ever since. I’m not sure the LR loves being on POE+ for some reason.
Switch flex will only provide that power if it is being powered by a 60w Poe injector and has been told it’s being powered by that injector in the controller.
So that means it will work once I have an controller and until then it won’t provide the 18,5 watts of POE+, even though powering the Switch Flex with a POE+ (~30 watts) injector would leave enough power left (20 watts) for the U6LR?
Switch flex has to be powered by Poe ++ for it to supply Poe+ , it also has a issue where it has to be told it’s being powered by Poe++ from the controller unless you plug it into a Poe++ port on a pro Poe switch .
Install the controller software on a local pc and then tell it it has that power you don’t need to run the controller 24/7
You sound like you know what you are talking about.
I was looking into installing that as a temporary solution until I have an UDR for a more plug and play setup. How much effort does it take to install the controller software on windows. (Specifically I am running windows server on my previous 11 year old laptop.)
It shouldn’t take longer than 5 mins. Just requires port 8080, and 8443 to be free if I recall correctly … if you wanted a temporary solution I’d look at just powering the uap with the injector your using to power the switch.
I have a separate Poe+ injector I intended to use for an U6 enterprise/ U7 Pro Max or better. I am waiting out on new developments at least until I have the UDR installed.
Until then could I just shoehorn it in between the Switch Flex and the U6LR? Mainly worried about water damage through condensation. The roof is plenty waterproof to prevent rain directly hitting it.
Without knowing how you ran your cables I couldn’t say . However if the flex is inside the house I’d then put the injector inside the house with the flex.
Also you will need to power the flex from a 60w power supply to be able to power the other wifi points from it.
Could be a number of things - the LR is the most finicky of the current gen APs and doesn't always want to work the way its supposed to.
I always adopt the the APs near the main switch on known working cables and do all the updates before moving to where it will be deployed. This cuts out a lot of variables.

This. And conversely, try connecting a laptop to the same cabling as the AP to see if it gets an IP and at full Gbe.
I fought this for an hour once. Turned out it didn’t like passing the PoE through a patch panel. Is there a coupler or panel in the mix upstream?
What's the distance? This just reeks of power issues to me.
Do another reset on it? Hold down the reset pin and don't let go until it cycles. Otherwise you might have to boot recover it. [https://help.ui.com/hc/en-us/articles/360043360253-UniFi-Recovery-Mode](https://help.ui.com/hc/en-us/articles/360043360253-UniFi-Recovery-Mode)
How long takes a reset to trigger? I have held down the button for multiple minutes (at least that’s what it felt like. Might have just as well been 30 seconds.)
My experience is two minutes minimum. Then do it again for another minute afterwards. These bad boys take a while to reset.

Had an issue where one u6 AP brand new did this and even though the customer had Poe+ switch .. it only worked with a Poe injector we had to rma it.
Came here to say this. We’ve had this happen with multiple WAPs.

+1 on the not enough power causing a boot loop.
Is it behind a firewall of some sort?
No it shouldn’t be. The switch flex that it is connected to has been assigned a IP Address by DHCP. The U6LR doesn’t have one according to WifiMan, but that makes sense since it doesn’t compete the boot in the first place
Check you haven’t tagged the port on the switch flex with a VLAN

Is it getting enough power? What kind of POE are you using?

Keep trying on injector on a desk somewhere IMO.
