Fail to join with TTN Europe 868 MHz. Worked 3 weeks ago.

[HelgeFH]

Hi, Today I tried to join a new device with a well tested software via OTAA. It fails with "Too Early".
I have another device that have been running fine for more than 3 months and I tried to reset it for it to rejoin. I am getting the same issue. It can not join and TTN say "Too Early".
I have tried setting Join data rate to SF12 and also SF9.
Anyone else with the same problem and do we have a solution for the issue?
Thanks

This is an issue with your internet connect & gateway - quite a rare and niche one - that means between it and the LoRaWAN Network Server the gateway thinks the send the join accept message is about 7 weeks too early.

Google shows several hits on the TTN Forum where Jac Kersing, @CaptainAwesome's big brother, explains it all.

This can't be fixed by RadioLib, it only a faster or less latent internet connection can resolve this, details on the TTN forum.
