Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can 
Nextcloud version (eg, 20.0.5): 25.0.3
Operating system and version (eg, Ubuntu 20.04): Fedora 37
Apache or nginx version (eg, Apache 2.4.25): 2.4.55-1.fc37
PHP version (eg, 7.4): 8.1.15
The issue you are facing:
All SMB shares are marked with exclamation mark and cannot be mounted.
SMB shares cannot be mounted using Nextcloud GUI, removal and creating them anew does not solve issue. However, I can mount said shares directly from Linux console.
All shares were working fine in 25.0.2.
I found no logs in php-fmp, messages, httpd logs, etc. Logs in nextcloud.log paster below in formatted version.
Enabled or disabled SElinux does not solve the issue.
However, I was also doing maintenance Fedora update on the same day. First, NC was updated from 25.0.2 to 25.0.3, followed by Fedora update.
Entire system was updated, those two is just example of version update:
php from 8.1.13-1.fc37 to 8.1.15-1.fc37
httpd from 2.4.54-5.fc37 to 2.4.55-1.fc37
samba from 4.17.4-2.fc37 to 4.17.5-0.fc37
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
- Have configured SMB shares
- Update NC from 25.0.2 to 25.0.3
- Exclamation marked at every share without possibly to mount them correctly
