I use Teams and cloudflared to access a home server (private IP) from Android for about six months. I periodically have issues where Teams has issues connecting (“Connecting” state or “Waiting for network”) that I usually can resolve by pausing/unpausing teams. While away from home yesterday, I was unable to access my home server. The tunnel appeared to be up since I could access the server via a browser using Google authentication. The DNS log did not show anything interesting. I displayed and uploaded the console log to OneDrive. I have had no success displaying the Boringtun log.
I still had issues when I returned home and connected via WiFi around 14:50 (even on my home LAN, Teams routes traffic through the cloudflared tunnel). I repeatedly tried to send feedback but got “Failed to create request” well into the evening. Pausing/unpausing, stopping/restarting Teams, and rebooting the phone did not make a difference. Again, the DNS log showed nothing interesting, and I uploaded another console log. On the home server, I noticed a lot of “Serve tunnel error error=‘connection with edge closed’” for ORD and IAD but only one for YYZ (successfully recovered) which should be my closest Cloudflare site. I started to notice general Internet connectivity issues in the evening with K-9 mail hanging. Again, rebooted the phone did not make a difference. K-9 started to work fine as soon as I stopped Teams.
This morning, Teams was working fine. When I looked at the uploaded console logs, they started at 2021-12-06 and ended at 2022-01-01. The console log on the phone shows just the last 24 hours. I displayed and used the Share feature a third time - same old data that did not include the most recent information.
Was there an issue with Cloudflare in the Toronto/Ontario/Canada area yesterday? How do I go about saving the Console and Boringtun logs? I installed an app on a Tab S2 device running 1.1.1.1 that will display large text files like Boringtun but saw the same truncated data with the most recent information missing.
Thanks, Norbert
