Zulu is dismissing the calls after generating new letsencrypt certificate

Please anyone why I am facing this error

All the extensions got unregistered.

One more test with the ucp softphone what we observed is when trying to call from zulu app it says dismissing in 4 and transfers the call at ucp webphone below and we answer it, it start calling and call ends well.

anyone known to this issue?

If webrtc clients are failing after a cert renewal, then it’s possible Asterisk needs a restart to load the new certificate.
