I keep getting that warning every few hours and I can't figure out why but I think it has to do with me losing access to the web interface both locally and eventually even from the home machine. I can see SABnzbd running and I can pause it with the icon but I can't access the interface until I restart it. I had to add some spaces to the log because the forum was acting like they were links and wouldn't let me post.

Is your SABnzbd reachable from Internet?
If so, the TLSV1_ALERT_UNKNOWN_CA is probably caused by nasty scanner / robot.
And ... really? Do you really loose the connection? You mean, after that, you can't access SABnzbd anymore? That should not happen. If so; which webbrowser do you use?

I am getting this exact same error every hour or so. It started a few days ago. I haven't made any changes to my usenet accounts. But Radarr updated recently. Could that my causing a problem?
When the error occurs, the web page (which is local, on the same pc as sab) stops updating. Once I close the window and restart Sab (by right clicking, troubleshoot, restart), then reopen the interface, it works fine until the next error. My Sab is not accessible to the outside.

Well, I may have figured out the problem. When I said Sab isn't accessible outside my network, I meant that I don't log into it from outside. But I did have the checkbox checked next to "Enable HTTPS" in the General Settings tab. I thought I had this checked so my indexer site could send NZBs to Sab...now I'm not sure.
But I unchecked that box and have not had an error in a couple hours. My indexer has not needed to send NZBs to Sab during that time, so i don't know if that still works or not.

So it looks like unchecking that HTTPS box prevents adding nzbs from sonarr/radarr and from my indexers website. i can still download the nzb and click it to add it to my Sab queue.

Usually only reachable right after a restart of SABnzbd.
What does that mean? Some program is stopping the traffic?
I can't access it at all. I see the process in task manager and I can right click the icon in Windows and still control SABnzbd but the web interface keeps loading with no end. I'm using Chrome right now and it isn't accessible with NZB360 or with Chrome on my phone, whether I'm using the local network or 4G.
Also SABnzbd has no problems downloading files. Sonarr and Radarr have no problems grabbing nzb files and sending them to SABnzbd. And Sonarr and Radarr have no problems being accessed outside the network.
EDIT: Now I can't seem to even get a connection on the local network. Only on the PC that SABnzbd is running on.

Oh, you can access SABnzbd?! From your local computer it works? ... does that change your title?
Please be clear and specific.

Only right after restarting SABnzbd, after a few hours I can no longer access the interface

OK, that's clear.
First setting SAB's logging to +Debug (via the Wrench). Let SAB run until you get the error again.
Then, On the computer running SABnzbd, find the file sabnzb.log. You can get it via the webinterface : Wrench in upper right corner -> Status tab -> Show logging. That will download the file. Post the last two pages on pastebin, and post the URL here with space around the dots (you're a new user, so otherwise spam protection kick in).
Or get the file via File Explorer.: %userprofile%\AppData\Local\sabnzbd\logs\sabnzbd.log
That way we can analyze way is going and probably solve it. Better for you and SABnzbd.
Or if you do not want that, just want SABnzbd working again, do this: in SAB's webinterface
http://127.0.0.1:8080/config/general/, uncheck "Enable HTTPS", and restart SABnzbd, and you will not get the error anymore. Maybe much easier.

FWIW: TLSV1_ALERT_UNKNOWN_CA ... if it is really TLSv1 (not TLSv1.2 or higher), it's a very old, unsafe protocol. It would mean some old outdated client (web browser, or API) is accessing SAB. It might also be a very bad firewall/virusscanner acting as a man in the middle (which is bad by itself).
Unchecking "Enable HTTPS" will make it go away.

Hey All,
Not sure what's happening here, but sabnzbd is throwing warnings, with no particular cadence that I can discern, that all look like the below (note, had to take out some periods here because the forum thinks I'm posting links):

Triggered by that post: @ykjr101 ... what version of SABnzbd do you use? If not 3 ... same advice: upgrade to SAB 3.1.1

I'm on 3.1.1. I switched off HTTPS. I'll see how it goes the next few hours.

For the record: were you already on 3.1.1? Of did you upgrade? If so ... from which version?
