RedisException: read error on connection to 127.0.0.1:6379

[tacruc]

Hey, thanks for your amazing app. I quite regularly get this error in my log. Do you have any idea if it can be fixed, or why my be the issue?

Does it happen when the android app reconnects to the server, for instance when you switch airplane mode off/on ? If so, it is a known issue and need to be fixed. It should not happen too often

Reconnecting was a good tip. Yesterday, I logged out and back in from the app. At this time the errors in the logs changed to:

This Error can be reproduced by reconnecting (airplane mode on-off). So possibly related to #8.

[p1gp1g]

So, this error is known and can be ignored, unless it happens every x minutes. I've to patch the code to catch the error.

The first one is different then. Any clue when it happens, or how to reproduce it ?

PS: you forgot to redact the device token 24e[...]; You should reconnect on nextpush android.

Thanks :+1:

[tacruc]

After relogin I cannot reproduce the issue. I will tell you if it reappears.

[tacruc]

Ok, now the error is back. I assume it is related to the fact, that the Redis service restarted. In detail:

1. Server Reboot
2. Redis didn't start due to the wrong start order
3. Errors in the log that Redis is is down.
4. After a while started Redis manually

Now the error is back.

[p1gp1g]

It happens when the redis is disconnected or even after the connection is back ?

[tacruc]

Quite regularly after the connection is back.

The problem is probably fixed with the release 1.0.5

@DonPicciotto : Which version of nextpush server do you use ? Were you able to reproduce this bug ?

Yep, still have this in log 2022-08-19T10:17:46 UTC

I use latest nextpush version from the store

[DonPicciotto]

Oh, wait, maybe I'm just really dumb. I deleted the block "location /_matrix/push/v1/notify" in nginx and the error is gone (until now). Maybe the problem was that since... I have nextcloud on standard port 80/443

[DonPicciotto]

It started again, sadly, even without matrix lines
