("bad handshake: Error([('SSL routines', 'ssl3_get_server_certificate', 'certificate verify failed')],)",)

Dear Team,

I’m getting this error “****(“bad handshake: Error([(‘SSL routines’, ‘ssl3_get_server_certificate’, ‘certificate verify failed’)],)”,)” while try deploy a new form. And getting this error “Unable to verify the first certificate” for existing form or project.

Previously, we were using SAN certificate and all were working fine. Now I have purchased a wildcard certificate and deployed it here; the above mentioned errors are started after deploying this wildcard certificate.

Did I missed anything? Could someone help me with the correct steps or suggest me to fix this error?

Thanks in advance.
