I have been caught up in a nightmare of a situation, and I hope this info helps someone else with a similar issue.
I have a website (Clutter Healing) that went down due to a “525 Handshake error” from Cloudflare; it has been working perfectly for over a year. No warnings, it just went offline. The site is hosted at Ionos, NS point to Cloudflare, and I used a Cloudflare generated certificate, installed in the server. This has worked perfectly for over a year.
The Cloudflare-generated certificate is showing as valid; the site can be pinged, everything is intact; it just won’t handshake.
I have also tried:
• dropping down from “strict” to “Full” - no success
• pausing Cloudflare - no success
• re-issuing the PEM & KEY, and re-installing - no success
Lastly, I tried to buy up a tier of support in Cloudflare, sine there is effectively zero support (other than in this forum… I hope someone can help me!). NO response to email or support tickets, and the site has now been offline for days. Please offer a paid tier of support!
My ONLY recourse now is to bypass Cloudflare altogether, use Ionos NS (they will ONLY issue their certificate if I use their NS…). IT WORKS. So, the problem is clearly with Cloudflare, but since I cannot get any help, support, or useful suggestions other than “look at the Help files” (which I did, and tried a number of unsuccessful changes) I can no longer reliably use Cloudflare.
So if I am forced to use Ionos NS to use an Ionos certificate, how would I use Cloudflare for the other services? I found a number of people with the same issue, and zero successful fixes. Has anyone come up with a solution?
Any help would be appreciated, this has been awful.
