I recently discovered an issue with my company’s domain in Firefox, giving the error SSL_ERROR_RX_RECORD_TOO_LONG. After contacting my hosting service, they believe the error is stemming from an incorrect IP address on file with CloudFlare. This was their response:
Did you used to have this site running through Cloudflare? Firefox can use DNS-over-HTTP which uses the records at Cloudflare and those are incorrect. If it was, then updating the “A” record there should fix the issue for everyone.
My issue is that in the ten years I’ve been with my company, we have not used CloudFlare and nobody here remembers using them in the past. I figure we must have at some point, but I obviously do not have access to this old account. (I created the account I’m posting with just to contact support, which has thus far been unhelpful.)
Essentially I am attempting to:
Confirm we previously held a CloudFlare account.
Either access this account to change our “A” record as noted above or
Request this change be made by CloudFlare without accessing this account.
Thanks for the reply, sandro. My hosting company seems to think Firefox is pulling an IP address from CloudFlare. Here’s more of their response:
Based on our tests, it would appear that is the root issue. One of our techs (running the same version of Firefox) was getting the same error as you were. They then disabled DNS-over-HTTP and the errors immediately stopped.
My Firefox install was not set to use DNS-over-HTTP and never could replicate the issue. I set my computers hosts file to use the ip 107.152.107.43 for the site and then tried to load it in Firefox. That enabled me to get the same error as was reported. If you want to try disabling DNS-over-HTTP you will find it in Firefox - Settings - Network Settings near the bottom of that page.
Additionally, they just provided the attached screenshot that appears to suggest our website was with CloudFlare 11-12 years ago.
Then you should clarify this with them, as their understanding is obviously wrong. Your nameservers point to aforementioned service and not Cloudflare.
@sandro Thank you very much for your help - I really appreciate the replies. The hosting company was able to resolve the issue by doing the following (which I believe is what you were getting at).
I believe we may help to get this issue fixed if we correct the nameservers listed on the registrar. Please take a look at the following:
