Verify that the SSL certificate you have created is valid. You can check if the “valid until” is a valid date or you can try to create another SSL certificate.
Also, try disabling “Strict RTP” to see if the problem comes from this setting.
I have checked SSL there is no problem, because it has only been 3 days since I installed vitalpbx and used SSL letscrypt according to the vitalpbx manual.
Currently, I have disabled strict rtp. I will try the next few days, if an error is still found, then I will report it again
