What is the issue you’re encountering

Server to CF connections have started to drop. Been using it without any issues for the last 6-ish months, but for the last couple days I’m seeing a lot of these errors in the log. Loading webpages gets stuck, file upload/downloads stall for a few seconds, before things settle down.

What steps have you taken to resolve the issue?

1. Tried refreshing tunnel tokens.
2. Updated/uninstalled/reinstalled cloudflared from 2024.11.x to 2025.1.x
3. Switched to cloudflared docker container as well

Wonder if you could change the protocol and run your tunnel over HTTP/2 instead of QUIC Might be some ISP issue.

@fritex Thanks for your reply. My bad, I forgot to mention this, but I tried switching the protocol to HTTP2 as well, but to no avail.
The error log changes slightly, but I see similar behaviour.

PS: Not sure it this could be related, but I recently started using AdGuard Home as well, running on the same server as the tunnel, could they somehow be connected? Though, I don’t see any CF-relevant queries being blocked/dropped on AGH.
