SSLforFree/ZeroSSL: Issues Renewing Free Certificate

I’ve been using SSLforFree for years, but since the switch to ZeroSSL, I’ve encountered some weird hiccups during the renewal process for free certificates. Despite the odd steps involved, I’ve always managed to renew and generate a new cert without issue—until now. My certificate is set to expire within 30 days, and I’m having no luck renewing it this time.

Do I need to revoke the current certificate and create a new one? I’m concerned that if I do, I might end up without a working certificate.

Any suggestions or alternatives? I’m ideally looking for a service with a web GUI similar to SSLforFree/ZeroSSL. I’ve considered Let’s Encrypt before but found the process frustrating.
