It should be possible to check if the error is related to a lost connection, otherwise this might lead to a lot of bandwidth usage if the chain storage read failed for another reason

Agree we should distinguish these errors if possible.

Isn't it best to just rebuild the connection anyway, just in case the error matching is too specific? (e.g, error on jsonrpsee rather than on the socket level)

Don't bail on parachain connection error. Instead, try to reconnect next block. Note that the startup behavior is unchanged, in that failure to connect upon startup is still considered a fatal error (which is useful in case the user supplies in invalid url: they get fast feedback that it's not going to work).
