Hello @pabloelcolombiano. Thanks for the update. Updating the line to fastcgi_pass unix:/run/php/php8.2-fpm.sock; did the trick. I did indeed updated php to 8.2 because passbolt v4 works only with newer php v8 as described in the update guide.
I suggest updating the documentation on this, so future updates are being done without this complication. Or even better, if it is possible to make it a part of the update, to use php v8 as dependency and change the config files of passbolt as described above.
I am sorry for the late response. I was on vacation.
Just a note for verification of php version support in case others are following, v4 Release Notes say:
Passbolt now requires a minimum of PHP 7.4 to run, but also supports PHP 8.2, which means faster performance and security. The browser extension is also getting a bit of love with some much needed maintenance to Manifest v3 and it requires at least a Passbolt API v3 to run.
