honestly here is the best place to ask
theres no support, no public team, no ticket system, no live site just the placeholder they put up every 6+months with same template
no real documentaion only community stuff, and no ONE place for all those documents (maybe eth wiki?)
good luck!
and as far as your errors good luck on that, eth gives so many different errors for everyting its impossible for one straight answer to help you, but they might! haha
