I configured a WR31 router with Ethernet WAN Failover to Cellular/Mobile
Everything seems working. When the Wan connection fails my PPP 1 LTE link is up and all connections are routed with a new static route.
When the Wan returns to operations the PPP1 link is down which is expected and all trafic is passed through the Wan.
To receive notifications whenever the failover is triggered I configured the Mail and SMS (Event Code and Event setting)
However I am stuck with the configured SMS alerts.
I have had some SMS fired succesfully during testing but now for some reasons this does not work anymore.
A timeout can be seen in the Event log but I am clueless

Any help would be appreciated.
