INVALIDATED events on SOKOL testnet network (xDAIchain testnet)

[Juan-cc]

Hi, we've been using image: eventeum/eventeum:latest (linux/amd64 DIGEST: 9ed093e0d8ea) for a while on xDAI testnet (called SOKOL testnet), and since last week we are receiving INVALIDATED on MOST of the Events we registered to.

1. Any idea how to prevent this from happening and start receiving CONFIRMED events again?
2. Which would be default EVENTEUM params for a network like xDAI?

NOTE: SOKOL is transitioning most nodes to Nethermind.

Thanks in Advance!!
