Dynamic connection seems to be using the wrong user some of the time

I'm getting an error in my error log saying that access is denied for user vinesine_alf-loc'@'localhost'. According to my connections file it shouldn't be using that user. It's not happening all the time, and I can't seem to pinpoint what file is calling it when the error occurs

Adding private message content

Could it possibly be a cron job running on the server? Would that resolve to my domain name or localhost?

How is the CRON running? Is it possible it is using the IP address instead of the domain to access the site? I suppose a CRON could use localhost as well, but you should be able to control that and have it use a recognized domain.

Maybe add the IP address to the list of domains? The problem is that somehow someone or something is accessing the site using a different domain than the ones you have listed. You just need to figure out how that would happen and account for it.

Another temporary solution would be to set the default connection to the live settings so that they will work when accessed from a different domain.

Do you know of a way to force the cron to use the domain?

Adding SERVER_NAME=mydomain.com before the cron script works

Ok, that actually caused an error, but this is currently working if anyone needs it.

wget https://mydomain.com/filename.php -O /dev/null >/dev/null 2>&1

Don't ask me what it means or how it works. I didn't write it. lol
