Can't set up a server and can't figure out what is the meaning of error. Linux Ubuntu 22.04

Here’s what I got.

No admin domain set. Select an option below:
Enter '1' to input manually
Enter '2' to configure through TakingNames.io
1

Enter admin domain:
trustedapi.space
2023/10/09 19:15:54 trustedapi.space: obtaining certificate: [trustedapi.space] Obtain: [trustedapi.space] creating new order: attempt 1: https://acme-v02.api.letsencrypt.org/acme/new-order: HTTP 429 urn:ietf:params:acme:error:rateLimited - Error creating new order :: too many failed authorizations recently: see https://letsencrypt.org/docs/failed-validation-limit/ (ca=https://acme-v02.api.letsencrypt.org/directory)

I don’t know what I need to do further. I’ve followed the instructions from site. Changed the sshd_config but it didn’t change a lot. Is there anybody who faced the same problem and solved it?

It looks like you’re hitting Let’s Encrypts rate limits from too many failed cert requests. You’ll need to wait a while to try again for that domain. You can run boringproxy with -acme-use-staging true to switch to the staging environment. That won’t give you a true secure cert, but it will let you test to make sure everything else is working before switching back to prod.

Thanks for your reply! I’ve already launched a tunnel through the cloudflare services. So there would be no possibility to test it.

No worries, Cloudflare is definitely easier to use than boringproxy
