calendar couldn’t be updated
contacts new version available: 4.0.8
contacts couldn’t be updated
richdocuments new version available: 5.0.2
richdocuments couldn’t be updated

any help appreciated…thank you

apparently not. So we’d need more info about your instance(s), environment and installed apps/software

I am running on

Operating System:Linux x86_64
PHP Version : Version: 8.0.16
MySql version: 10.3.32
Nextcloud : 23.0.2

Every time I tried to update the apps…error shows

GuzzleHttp\Exception\ConnectException: cURL error 28: Operation timed out after 150000 milliseconds with 0 out of 0 bytes received (see for

I’ve been pulling out my hair trying to fix this problem…but no luck.

r u sure that there’s no built-in firewall blocking your system?

I never tried to run NC on a windows built-in linux… I do remember that there were several problems with that kind of setup at times.

Maybe a VM would be better?

I’m not entirely sure whether it’s the built-in firewall from ubuntu or the firewall from wsl2/windows that causing the problem.
I just find it strange, cause I was able to upgrade the nextcloud from version 23.0.0 to 23.0.2 without any issue.

I have also tried opening the port at the powershell with this command
netsh advfirewall firewall add rule name= “Open Port 80” dir=in action=allow protocol=TCP localport=80
New-NetFirewallRule -DisplayName “WSL” -Direction Inbound -InterfaceAlias “vEthernet (WSL)” -Action Allow

But still can’t update the apps…

Uninstall ufw on your system. You do not need it.

I have tried the command “sudo ufw disable”…reboot the server…still can’t update …perhaps do you mean remove the ufw totally?
like sudo apt-get remove ufw or sudo apt-get purge ufw?

If it is really disabled i think it is fine and you must not uninstall it.

Can you test a direct download on the server e.g.



You can download in a tmp dir e.g. /tmp. Please post errors.

I am getting the below;

curl: (35) OpenSSL SSL_connect: Connection reset by peer in connection to

Any ideas how to fix this?
