I am getting Connection error - caused by slow rest/events endpoint #9440

Closed ieugen closed 8 months ago

ieugen commented 8 months ago

Hello,

I am getting this error notice . I have traced the cause to the rest/events endoint being slow to respond for whatever reason. It takes 1min to respond and the UI seems to give up before a response comes through. I have a powerful enough computer and low syncthing usage (~30GB) to exclude performance issues .

Firefox ESR 115.x

I opened up Syncthing web gui and I constantly see the error dialog. It's very annoying.

The events endpoint returning after a minute is expected and doesn't cause a GUI error. Your root cause is something else. If you're using a proxy, it needs to allow requests that take over a minute to respond without returning a timeout error. I suggesting turning to the forum for troubleshooting if you don't figure it out on your own.

hi @calmh , I am not using a proxy. I am running syncthing 1.27.3 on a raspberry pi 4 and I don't see issues there (same browser on same computer). I see the error only for local syncthing.

It might be something with the build for Debian or my setup. I disabled firewall and also restored the port to it's original. I still get the error.

I will try the forums perhaps as you suggested. I don't have any idea of what might be wrong.
