@Contemporary_Mgmt I dont think you can use hologram cloud with a device that does not have a hologram simcard, so if you switched SIMs away from Hologram you will have to use a different cloud messaging service (AWS and Azure have some).
I’m also confused what you mean with “my server running cron job without any interruptions” but “I have not been able to connect to Hologram network for 22 days…” You first sentence says everything is working but the second one says you have no connection to Hologram?
