The provided fragment of the log does not show the error itself.
Could you please share the part of the log where the error occurs?
It could be the bnb-shkeeper log or the shkeeper.io log.

We can confirm that such an error can occur during the backup of BNB keys with a large number of generated addresses.
This is due to the fact that the time spent on decrypting the keys is greater than the response timeout from bnb-shkeeper
This will be fixed in the next releases of bnb-shkeeper

For Tron there should be no such error
Please share tron-shkeeper log to identify the problem

It seems that there is a problem with decoding one of the private keys.
We have not been notified of such an error before.
You can try to check the encoded private keys by retrieving them from the database and visually confirming that they are of the same type (in terms of length and initial and final characters).
You can do it with the following command:

sqlite3  /var/lib/rancher/k3s/storage/pvc-*tron-shkeeper-data/database.db 'select * from keys'

If any key stands out, it is most likely the cause of this failure.
If you have not changed anything in the database manually, please check the storage for errors.
