Solved Nextcloud issues.

Installed Nextcloud a while back and ran into some issues. I immediately ran into some health/family issues so I left if as it was and am now just getting back to it..

I feel like it could be something to do with mysql, but I'm not proficient enough with it to just go rooting around in there without at least a little guidance.. But I can tell you that the DB as well as the user are installed..

root@localhost [(none)]> SELECT User FROM mysql.user;
| User |
| mysql.infoschema |
| mysql.session |
| mysql.sys |
| [B][COLOR=rgb(44, 130, 201)]nextcloud_user[/COLOR][/B] |
| root |
5 rows in set (0.00 sec)

Any help would be greatly appreciated...
check nextcloud db config (verify it's set to pdo_mysql or something)
also check php -r 'phpinfo();'|grep mysql

Not sure how to check the Nextcloud DB config. In MySql?

A reinstallation of those apps - MySQL, nextcloud etc. may fix it. If other database apps work fine, perhaps you can reinstall/upgrade nextcloud only. An update was push into freshports earlier this month. Your data go no where.
I have no clue about Nextcloud, but maybe it uses the "MySQL Improved Extension" / mysqli to perform MySQL requests (package "php80-mysqli")…

Turns out mysql80 has switched over to a new authentication method that is incompatible with PHP in some way.
The corrective actions prescribed HERE is:

In MySQL 8, a new auth plugin was introduced: caching_sha2_password. That plugin does NOT work with PHP because the PHP's mysqlnd has NOT been updated. PHP 7.2.4 or higher will work with the OLD auth plugin (mysql_native_password) if you convert the mysql user account PHP connects to the db with to the old authentication! ALTER USER 'user_name'@'hostname' IDENTIFIED WITH mysql_native_password BY 'password'; In your /etc/my.cnf file you can add: default_authentication_plugin = mysql_native_password But this default only works for all new accounts created going forward.

It's one of the reasons some people stick with he long existing versions - mysql-server-57 & php74. You may rollback or continue hacking and prepare to effect the changes at every upgrade until those changes are pushed upstream.
