Twilio Callback stopped working

Your software
My Mautic version is: 5.0.3
My PHP version is: 8.3.8
My Database type and version is: phpmyadmin 5.2.1

Your problem
Starting on 7/19/24 Mautic stopped receiving the Twilio Callback. It was working perfectly before that date.

My callback URL is: https://xxx.mydomain.com/sms/twilio/callback

These errors are showing in the log:
Flow Event = Timeout

Steps I have tried to fix the problem:

  • Contacted host (EasWrk) to see if there was an issue, no issues could be found on their end.
  • Increased timeout in Studio flow to 3 seconds

Yet situation still persists.
