    Hey there!  I don't believe the issue mentioned in that older thread is related to your issue here.  While these are definitely entries in the logs, it's impossible to say what is causing them without additional details on what is happening.

    Can you check the main Apache log around that time to see if there is any other information?  If not, I would personally just ignore these entries.

    Hi thanks for the reply.

    So I found the matching entries, first entry is from the dom log, the other two are from the apache log, they show some SSL issues:

    75.71.93.103 - - [07/Feb/2025:08:15:24 -0600] "GET /scu/google/thank-you.php?stock_number=SCU6673 HTTP/2.0" 421 322 "https://form.sellcarus.com/" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/132.0.0.0 Safari/537.36"

    Any help?

    Thanks a bunch

    Obviously some issue with the SSL setup. The use the same SSL certificate as far as I can see.

    Where could the error be?

    Thanks for that information.  More details on that can be found here:

    https://support.cpanel.net/hc/en-us/articles/1500004701722-421-Misdirected-Request

    but was this possibly a wildcard SSL that was installed?

    Thanks this seems to help.

    Well it used to be a wildcard certificate. Now there is one that is used for form.sellcarus.com and www.sellcarus.com, they are the same.

    We did have a similair issue with the wildcard one so it was fixed by getting rid of the wild card one, but there are still a few of these errors.

    Is it somehow possible to create two different certificates? I think that might fix this right?

    In cpanel it is listed seperately but the details show it is the same certificate.

    This is our setup regarding this.

    The only way to get different certificates would be to have each of the domains on a unique cPanel account.  What you're showing in that screenshot looks like a normal configuration to me.

    At this point I'd recommend creating a ticket so this can be investigated directly on the server.
