Fatal BWL JWT Parsing Error

[Mavrap]

Describe the bug With the latest cloud update I get "Fatal BBL JWT parsing error". After that the display restarts.

To Reproduce Steps to reproduce the behavior:

update with the Firmware.bin Create config.json with the online tool Save the config.json to sd card reboot display Expected behavior I expect to see the standard view of the display with temps and menu.

Screenshots Actually not possible, sorry. but the software loops : Connecting -> connected -> Checking for OTA update -> Processing JWT Token -> Fatal BBL JWT parsing error

XTOUCH (please complete the following information): last firmware

FW: Latest OTA Printers (please complete the following information):

Device: P1S FW Version: 01.06.00.00 AMS units: 1 Additional context On start it shows "Connecting -> connected -> Checking for OTA update -> Processing JWT Token -> Fatal BBL JWT parsing error". 2FA is disabled. I changed my password without any effect (Bambulab account)

Same here since this morning too

Manually doing the steps the code does, seems to work fine.

1. Getting the token via the login endpoint still works
2. Decoding the token still includes the username
3. Here is the log from the device:

[...]
Getting accessToken from Bambu Cloud
[ 14865][E][ssl_client.cpp:37] _handle_error(): [start_ssl_client():273]: (-9984) X509 - Certificate verification failed, e.g. CRL, CA or signature check failed
[ 14879][E][WiFiClientSecure.cpp:144] connect(): start_ssl_client: -9984
Received error: -1
deserializeJson() failed: EmptyInput

So it appers as the ssl certificate is not being validated correctly anymore. Not sure how to fix this.

I have two xTouch devices and both have the same error as of this morning. I formatted one of their SD cards and re-made the config file, but same error occurs.
