Unifi Heartbeat missed problem since update

[DalekSec]

Since we have updated to 4.8.12 our UAPs are randomly disconnecting and reconnecting. On the interface it comes up with 'Heartbeat Missed' and give it 5-10mins and the UAPs come back up by themselves. Has anyone else had this problem? We seem to be getting spammed with UAP Disconnected emails in the last week.

 

Thanks

Same here, not looked for a fix yet - I tailed the logs on one of the AP's but so far none have disconnected today... It's quite random. I updated due to putting some of those new AC Pros in

[DalekSec]

Same reason as us, got the new AC Pros (which are brilliant I think). We have had loads disconnect today without sending out emails, only sends emails if they are off for a certain amount of time, which I haven't figured out yet!

[caffrey]

It is totally random, just noticed that we had one like yourself with no email went down an hour ago (I ordered by uptime in devices) I have just noticed that the unifi controller isn't apparently running - not sure when that happened (We use a 2012r2 VM for it)

[DalekSec]

Sounds just like our problem, we have ours on a 2008 R2 VM through. We did look at moving it to 2012 R2 but caused us a headache and had to revert back.

Just having a quick look at their forums now, seems related to this thread https://community.ubnt.com/t5/UniFi-Wireless/Intermittent-connectivity-loss-with-UAP-AC-PRO/td-p/1431847 I don't think we have much choice until a new version comes out, unless we try the alpha

[DalekSec]

Well found, plus side is not our servers fault, down side is will have to upgrade unifi again. Last few times we have done this it hasn't been easy! Had to restore from back-up several times.

[caffrey]

Same, I now download backup then install - it usually goes pear shaped involving restoration from backup. I usually leave it alone when it works but like me you got the new AP's so had little choice! I may just in future just uninstall and start from scratch, then restore

[caffrey]

New version out, https://community.ubnt.com/t5/UniFi-Updates-Blog/UniFi-4-8-14-is-released/ba-p/1495935

 

Includes :- [uAPG2] Adjustments which should help lessen intermittent connectivity experienced with some devices

 

I've just installed it (went on fine with no issues), and now starting a rolling upgrade - I'll see if there's any discos during the night

[caffrey]

None during the night, fingers crossed it's fixed it

[DalekSec]

Great, Thanks for the help. Think we are going to leave the update until Easter unless the dropping off access points are getting really bad.

Anyone had firmware not connecting to the controller 3.3.19.4015. I have ap stuck on Adopting. I do have two nics on controller.

[caffrey]

Have you SSH'd into the AP and adopted it that way ?

 

using :- set-inform http://yourserverIP:8080/inform

 

Incidentaly the AP's have been fine since the upgrade

[nicholab]

Yep I SSH'd in to the AP but it saying connection rejected if I go "info"

 

I used:

mca-cli

set-inform http://myserver:8080/inform

[caffrey]

I used to have an issue adopting and the only way I could get it working was set up a temporary controller on a laptop, attach the AP to it,adopt and upgrade then I'd forget the AP and readopt on the main controller

[nicholab]

Is it worth wiping the config on the controller? Or is it the AP's that are likely to be the issue?

[caffrey]

It's more than likely the AP, since upgrading and putting the controller on windows server 2012r2 I've had no issues adopting (Was hit and miss for me on linux)

[nicholab]

I looked at my AP they are up but they will not adopt on the controller. I did restore the configuration after updating the controller I am on BSD platform. Is there a way of removing ap from config?

[caffrey]

Removing from the Controller ? Properties / configuration / forget this AP

[nicholab]

Try that it tells me it is busy an an error has happened.

[caffrey]

Strange, unless it is due to your two nics - I believe that the controller / AP's need to be on the same LAN range, but I could be wrong

[nicholab]

Ap on same lan range but it still will not adopt. No way to remove uap what to do next. Can I down grade firmware?

[caffrey]

Sure, See https://help.ubnt.com/hc/en-us/articles/204910064-UniFi-Upgrading-firmware-image-via-SSH should work for downgrading too, although I've never tried it - YMMV

[nicholab]

Just tried adoption on a Windows machine and it works.

[caffrey]

Yeah that's the issue I had, then I upgraded / forgot the AP on windows then adopted it on my production linux controller
