Webmail ssl error since switching to VPS

Hello

the webmail not working since i switched to VPS hosting, i have a host with a2hosting i speak to the support they told me that the issue (SSL_ERROR_NO_CYPHER_OVERLAP) from cloudflare SSL certificate.

Works for me.

Retry in incognito mode or clear your browser cache.

no it’s not working

works.

the 4th level is not covered by your ssl certificate. It only supports *.stoprat.fr. Youre trying to access webmail.server.stoprat.fr.

When i click email accounts in cpanel redirect me to webmail.server.stoprat.fr. how can i fix this?
