I’m not quite sure what had happened but could this be a problem with the Firewall or DNS from Cloudflare?
Looks to be some issue with the certificate on your origin server, can you set ssl to Flexible for the time being to see if we can side-step the error?
Thank you, still an issue and settings look great. The 500 error occurs because your origin server (your web host) is returning this code to us, and Cloudflare returns this code in turn to your visitors. Can you contact your host to see the errors in their logs?
Reviewing your server’s HTTP access and error logs is a great place to start when these errors occur as they should confirm the response code is being returned by your web server (this is visible in your access logs) and give some indication as to why (this is visible in the error logs).
Well I’m not getting any replies from OVH yet but I think there maybe a bug in the OVH Web Panel as I cannot seem to remove the ovh.net Name Servers, for some odd reason. The OVH Web Panel under the DNS tab says "Our systems have detected errors while checking your zone. The latest amendments were therefore not taken into account. To remedy this, please correct the following problems:
line 10: *.apg-clan.org: invalid NS owner name (wildcard)"
OK I had a reply from OVH but they are saying that they don’t understand those logs that I’ve relayed from Cloudflare and don’t have further control…
Thank you for your response.
Your domain and website apg-clan.org is managed outside of OVH, hence, I do
not understand what logs you are referring to. For the logs of the server the
domain points to, you should contact Cloudflare.
For any other questions or concerns, please feel free to contact us through a
support ticket or by phone.
I’m kinda struggling to figure out why this is happening. However I suspect it could be a problem with my vBulletin forum software, but I cannot see any reasons why it would be behind this 500/403 error.
Hi @robocop, thank you. On the SSL/TLS app of the cloudflare dashboard, overview tab, can you set ssl to Flexible? It is currently off and causing a redirect.
Ideally, the server access logs for your origin server is where you’d see the error. Let’s also loop in Cloudflare Customer Support to see if they can diagnose more detail on the error.

Thanks for writing to Cloudflare Support.
A HTTP 500 error is a server side error that means that the origin web server had an error during the request. Cloudflare does not generate 500s, so this would indicate something is not configured correctly with your hosting provider. The best next steps would be to work with your hosting provider to identify the error that occurred by examining your error logs.
This is an automated response which we hope has answered your question. If you need further assistance, simply reply to this email to reach a Cloudflare Technical Support Engineer.

Cloudflare does not generate any 4xx error code, a 403 would indicate something is not configured correctly with your hosting provider or your client is sending something incorrect. The best next step is to generate a HAR file and send this to your hosting provider to identify what potential misconfiguration is in place.

Well also I might need to contact vBulletin to see if my forums is needing a fresh installation as I cannot seem to load AdminCP webpages or anything linked to vBulletin due to this error.
Hang on! I’ve just found out one of the files from my website was missing the class_core.php file for DBTech SEO plugin for vBulletin…but for some odd reason it was deleted. Luckily I’ve backed up my web files recently in December 2019. I don’t know how that missing .php file from DBTech vanished…
