Unable to sync ethereum mainnet

Following docs at

lots of such messages in logs:

WARN [01-24|09:47:44.328] Snapshot extension registration failed   peer=aab3bbde err="peer connected on snap without compatible eth support"
INFO [01-24|09:48:04.915] Looking for peers                        peercount=2 tried=37 static=0

There's definitely something fishy is going on with node startup, I had the same intermittent issue with BSC mainnet
Any help welcomed

If I remove snapshot=true from reader-node-arguments I see
Post-merge network, but no beacon client seen. Please launch one to follow the chain! in logs...
