Editing does not work anymore

Hey there,

starting today, we are not able to edit any pages in our Confluence Server instance anymore. The following error appears:

Bildschirmfoto 2020-01-06 um 13.13.36.png

Based on this article I disabled Synchrony, but it does not help: https://jira.atlassian.com/browse/CONFCLOUD-65514

I also restarted the whole instance; but still the same error appears.

Anybody knows that to do? :(

Hi,

based on your question - are you using server (in text) or cloud (tags) instance?

Can you share part of application log where is shower any error like this one? What is your Confluence version?

https://confluence.atlassian.com/doc/working-with-confluence-logs-108364721.html

Hey @Petr Vaníček

it's 7.1.0 – server. Sorry for the confusion :).

Attached, there are some logs:

Hi,

sorry, I had busy last week (including weekend).

From your logs it's not clear, but if it works before then it's weird. Something changed in something like proxy, firewall,...?

What about DB connections? We had similar problem with one of our customer.

@Petr Vaníček

the system is internal; no firewall or proxy changes. I now disabled Synchrony and restarted the whole machine; now it is working (which shows that the database is running correctly; it's on the same machine).

Switching back to Synchrony causes the same error.

Petr Vaníček Community Leader Jan 14, 2020

It's weird - there must be some kind of problem with accessing synchrony port.

With DB connections I meant usage - count of used and free.

Is it possible to change the port?
