There is very little that can be done. Aside from waiting for the weekly rate limit to reset, all that can be done is:
1. Selecting ZeroSSL instead of Let's Encrypt
2. Get a free SSL Certificate from https://sslforfree.com
What does your account panel say at https://x10hosting.com/panel
If it shows active, click on hosting control panel and navigate to Account Manager > Domain Setup > click the checkbox to the domain > click the Suspend/Unsuspend button
The weekly rate limit is not imposed by hosting, it is imposed by Let's Encrypt and ZeroSSL. The alternative is manually getting one from sslforfree.com
It is a weekly rate limit, this limit is imposed by the ACME Provider.
You can select whether you want the certificate issued by Let's Encrypt or ZeroSSL
All that can be done is either waiting for the weekly rate limit to reset, selecting an alternate ACME Provider, or manually installing one generated from https://www.sslforfree.com/
