Hello, I have a problem with a sending event reporting via mail on my 6 devices Teltonika RUT950. The devices stopped sending messages on February 4, 2022. I didn't change any settings and suddenly the routers stopped sending messages. Automatic messaging works on another device Teltonika RUTXR1 connected to the same network, with the same settings. SMTP server is set on smtp.office365.com and port 587, previously this setting worked. Sending a test message also fails. Firmware on devices TLT RUT950: RUT9XX_R_00.06.08.6.
