cannot deserialize packet / failed to establish connection with the node

Hello,

I am unable to synchronize carp from scratch in the preprod network. The logs show the following error message:

Resynchronizing Carp from scratch, including completely dropping the PostgreSQL database, did not resolve the issue for me.

This should be fixed when we merge https://github.com/dcSpark/carp/pull/187

Although if we are not going to merge that soon maybe we could port only the source-related changes from there to the main branch (which require updating dcspark core to the branch were we use pallas_network instead of cardano_net and updating some interfaces).
