Ttn-lw-migrate error

TTN V2 to V3 Upgrade Migrating Devices to V3
1

Hello,
Today it is impossible for me to migrate a sensor via the migration tool ttn-lw-migrate.

It shows me a connection error. (see screenshot)
Is it working with you or is the problem with me?

Bit hard to tell if it’s you or something else as the picture isn’t readable - perhaps you could repost the log as text, not forgetting to format it with the </> tool.

Sorry for picture.

What ISP are you on?

Thanks, it’s coming from my internet connection. It’s probably my company’s firewall blocking it.
I switched to LTE and no more problems.
