I guess you’re keeping an eye on Basic Station Integration: Race condition in re-connection handling causes permanent failure of uplink forwarding · Issue #1730 · TheThingsNetwork/lorawan-stack · GitHub but just to be sure: this introduced new problems with internet providers that reset the connection every 24 hours (and maybe also assigns a new IP address lease). From Slack:
Every morning the same problem The TTIG Gateway does not transmit data anymore
Thats exactly the same what i have seen as well. My ISP resetted the internet connection (which always includes new IP addresses) in the night from 2020-01-29 to -30 and my TTIG became trouble. Before that date, ISP resets were never a trouble.
Such an ISP-reset of the internet line takes normally appr. 90 seconds to recover.
