If anyone of you also uses Telekom D1 (APN internet.t-d1.de) with a public IPv4 address that allows accepting incoming connections, I can advise you to daily reboot the device (to force obtaining a new modem dial and fresh IPv4 address). I noticed that roughly after 24...48 hours of uptime Telekom blocked incoming connections partially, mainly originating from Telekom mobile data clients like my phone. It's kind of obscure, because connections originating from Telekom or O2 DSL I've tested still could connect to my server running on T-D1. I read somewhere on telekom-hilft.de in a forum thread, that this is intended behaviour of Telekom to keep business users away from running permanent servers with a static IP address while on mobile data APN internet.t-d1.de .

The workaround is: Put a daily reboot of your Quectel NR 7101 in place and since I did that, my incoming connections worked - regardless where they originated from.

Bei mir hatte er auch 5G-SA angezeigt aber ohne Signalstärke (N/A). Funktioniert hatte es trotzdem aber ich hatte mehrmals täglich nervige Reconnects.

Seit dem Upgrade auf FW „V1.00(ABUV.6)b2_E0“ und LTE-Modul FW auf „RG502QEAAAR11A07M4G“ läuft alles störungsfrei. Diese Versionen wurden mir zum Online-Update angeboten.
