Connection Error Code 26 after upgrading to FBOS 13.0.1

[Ascend]

Hello @Tom,

Farmbot OS v13.0.1 requires an additional port to be accessed.

Having trouble connecting (Code 26)? TCP Port requirements in FBOS 13.0.1 have changed

FarmBot OS v13.0.1 incorporates updates that will improve connection reliability. If you had a FarmBot setup that recently stopped working after a FarmBot OS update, you may need to enable access to TCP port 8883 on your local area network. This previously unused port is now required to operate FBOS. Please see this guide for a list of required TCP ports.

Please make sure that the TCP port 8883 is open and can be accessed by the device.
