As I'm in a place with a new IP address, I was running into issues with opening Coda projects. I was getting an error that went something like:
issuer is not trusted issue
This happened all of a sudden, hence my presumption that it's related to my connecting to my SVN server (Springloops) from a new IP address. The resolution was pretty easy:
svn list https://subdomain.sprinloops.com/repo/directory
Doing so seemed to make fixes across the board for all projects and repos that are hosted on that server/host. When you issue this command, it'll prompt you with something similar to the following:
Error validating server certificate for 'https://subdomain.springloops.com:443': - The certificate is not issued by a trusted authority. Use the fingerprint to validate the certificate manually! Certificate information: - Hostname: *.springloops.com - Valid: from Wed, 04 Apr 2012 20:19:54 GMT until Wed, 08 May 2013 18:07:56 GMT - Issuer: GeoTrust, Inc., US - Fingerprint: 33:fe:fa:6a:3a:22:0b:30:a7:c5:90:2b:72:7f:63:db:fd:55:2b:3a (R)eject, accept (t)emporarily or accept (p)ermanently?
Just hit the letter 'p', and you're golden :)
