Yes I can use nostr:npub1kvaln6tm0re4d99q9e4ma788wpvnw0jzkz595cljtfgwhldd75xsj9tkzv app and connected to their mint also; works fine
In eNuts app, connected to nostr:npub1kvaln6tm0re4d99q9e4ma788wpvnw0jzkz595cljtfgwhldd75xsj9tkzv mint, I get the above error. Been like that for a few days now
Ive done what you said ("...wait for some timeout issue to fix itself..."), but still persists.
