TXT Records, Take Two
🐞 TXT Records: only ONE string per record
Previously we were returning one TXT record with multiple strings for sslip.io. That did not work for ProtonMail's domain verification.
It seems a convention that each TXT record has one string. google.com, for example, has a separate TXT record for each string.
It turns out I had misunderstood the StackExchange thread.
fixes (from ProtonMail domain verification):
Verification did not succeed, please try again in an hour.
