Both display (different) certificates when I go to
On one, I can add the other as a Peer using
Admin->Networking->Peers, Add a new host.
On the other, it says, "There was a problem retrieving the public key."
I've read a number of threads on this, but only one that described this situation exactly (maybe not localhosts), and that was unresolved.
Are there any special circumstances that apply to networking 2 installs on the same IP (localhost)?
Thanks: I checked that the host URL in the Peers screen matched the $CFG->wwwroot setting (which doesn't have a trailing slash) and it did.
To anticipate another config file issue, both config files have the $CFG->opensslcnf set to point to openssl.cnf (this may be obvious from the fact that both installs find their own public key when you look under Admin->Networking->Settings.)
a slight tangent: when you see the message: "There was a problem retrieving the public key." , where is the public key actually stored (XP, if that's relevant)?
If you turn on debugging, you may get more information about why it was unable to retrieve the key.
And, of course, make sure that Networking is actually turned on (that happened to me the other day...).
