I was having trouble figuring out how to sign into Olas without pasting my nsec into it. My mistake was installing the "offline" version of Amber. It doesn't have the + icon on the application page, which is how you create an nsecbunker.
I updated the nostr notification provider in Uptime Kuma (fancy self-hosted monitoring tool):
Now it supports relays that require AUTH like auth.nostr1.com.
