I have hosting with IONOS
I have domain with 123-reg
As per instructions from IONOS I updated the NS on 123-reg to Cloudflare leaving IONOS alone. The site is active and recognised by Cloudflare but is inaccessible 525 error.
If I update IONOS nameservers also the same error persists.
I have tried flexible/off SSL and this does not help in the slightest (Too many redirects)
I can’t install custom SSL certificates on this shared hosting package.
What do I have left to try. If I use standard nameservers the site is fine. Tellingly i have other sites which use IONOS exclusively both in domain and hosting and they work 100% with Cloudflare.
Finally i have tried removing all SSL and rewrites and https, but that also did not help
