General Support: SSL certificate not installing
We are having trouble getting the SSL certificate working for our site. We have correctly set up the DNS for our host (www.kingstonmencap.org.uk) to point to Voice's IP address, and visiting the site without https works fine:
; <<>> DiG 9.14.7 <<>> +nocomments www.kingstonmencap.org.uk ;; global options: +cmd ;www.kingstonmencap.org.uk. IN A www.kingstonmencap.org.uk. 3599 IN A 220.127.116.11 ;; Query time: 577 msec ;; SERVER: 18.104.22.168#53(22.214.171.124) ;; WHEN: Thu Jun 11 09:52:33 BST 2020 ;; MSG SIZE rcvd: 70
But when we visit https://www.kingstonmencap.org.uk we get an error because the certificate is for a different (and entirely unrelated) domain.
Can you please help us to diagnose this?
Many thanks, -Paul
There had been a problem with that specific domain, and LetsEncrypt (from where the certificates are registered) was complaining that we couldn't get a new certificate as we already had too many. (there's a limit of getting five per week per domain)
I'm not exactly sure why it had rate limited that domain but none of the others on our system. I suspect a temporary problem with the domain had resulted in too many retries to get a certificate.
Anyway - I've been able to manually get a certificate for that domain and install it on the server - and from here on it it *should* be fine, and it should renew automatically when necessary.
Perfect, thank you very much! It is all working correctly now.
Perhaps it is our fault as we changed the settings for the domain a few times, so perhaps it was triggering the e-voice system to renegerate the certificate and we hit the limit?
Anyway, it is all correct now.
Thanks again for the rapid and helpful response.
Kind regards, -Paul
