Steps to reproduce

1. update to nextcloud 19.0.0
2. install ONLYOFFICE and Community Document Server
3. update to NC 19.0.1
4. go into settings->ONLYOFFICE
5. press SAVE

Expected behaviour

ONLYOFFICE should continue working after the update.

Actual behaviour

ONLYOFFICE document server worked fine since NC18, also fine under 19.0.1 until I pressed the SAVE button recently agian in settings.

Now I get this error:

The problem still exists after the update to 19.0.2

I also discussed it in the nextcloud help forum

This is the app settings before I click on the submit button:

Workaround:

delete the setting 'settings_error' with:

docker exec next-your-nextcloudorg_db_1 mysql nextcloud -p$MYSQL_ROOT_PASSWORD -e "delete from oc_appconfig where appid='onlyoffice' AND configkey='settings_error'"

[rubo77]

I just updated to ONLYOFFICE 6.0.0 and the problem still exists (and the workaround still works to fix it)

[RobertRoberts2020]

Workaround:

delete the setting 'settings_error' with:

docker exec next-your-nextcloudorg_db_1 mysql nextcloud -p$MYSQL_ROOT_PASSWORD -e "delete from oc_appconfig where appid='onlyoffice' AND configkey='settings_error'"

Do you know how am I supposed to apply this workaround from TrueNas?

[AlexanderProd]

I'm getting the same error with Nextcloud 20.0.7, OnlyOffice Nextcloud app 6.3.0 and OnlyOffice Document server 6.2 running in docker with a Nginx reverse proxy in front of it.

I have the same issue on TrueNas. Have you found a way to address this issue?

[rubo77]

Can't you just call this there?

mysql nextcloud -p$MYSQL_ROOT_PASSWORD -e "delete from oc_appconfig where appid='onlyoffice' AND configkey='settings_error'"

[ionics]

This does not seem to be a workarround. @rubo77 have you studied the code? this entry seems to get created when the connection fails. Literally this so called "workarround" does not address the issue itself. Just clearing a log entry from the database. Correct me if i am wrong. Just wanted the people not to waste their time in the wrong direction. At least this did not work on 'nextcloud' ubuntu 20.04 host to 'docker with onlyoffice document-server container' connection. Kind regards.

[rubo77]

Just clearing a log entry from the database. Correct me if i am wrong.

It's not a log entry, it is a config entry!

And it fixed the issue for me, so maybe there is something different in your case

[ionics]

@rubo77 in our case it was the docker container hosting onlyoffice document-server uses http while our old onlyoffice server used https @ the config for "ONLYOFFICE Docs address for internal requests from the server". Your so called "config" entry gets created when the connection fails. A config entry even its created under configkey with the value:

onlyoffice | settings_error | cURL error 7: Failed to connect to docs.example.com port 443: Connection refused (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://docs.example.com/healthcheck at least to me would be of no real meaning.

Switching to a proper config (in our case using http instead of https) fixed the issue.

[ionics]

this settings_error configkey is never created if no connection errors appear. So for future readers fix your connection settings and you are good to go. Running nc v23.0.0 with ONLYOFFICE (connector) v7.2.1 connected to docker onlyoffice document-server built by this docker-compose.yml

one thing left... in the container set rejectUnauthorized=true to false and restart with supervisorctl! services.CoAuthoring.requestDefaults.rejectUnauthorized=false in /etc/onlyoffice/documentserver/defaults.json file and restart documentserver serviceis with supervisorctl restart all.

For those of you who would like to use https instead of http which is advisable you have to change the nginx config in the container from using port 80 to 443 + add proper ssl certs or selfe signed / snake-oil once.

Good luck!

@ionics : why do you use extra containers for onlyoffice?

I use only an app container and a db container, and onlyoffice works fine with it I installed two apps: "ONLYOFFICE" and "Community Document Server"

On my host, I have an extra proxy-VM which routes all traffic and manages the certificates, so in the docker image everything is just http, and the proxy-VM serves it as https. maybe thats why I get this error again and again? (and my Workaround still works in NC23)

Change the /etc/hosts file in the nextcloud container and add 192.168.*.* onlyoffice.*.com (your domain name). Also add 192.168.*.* nextcloud.*.com to the hosts file of the onlyoffice container.
