Here are some facts I've gathered about this issue:

• This error is happening because ita fails to flush habitat configs.
• Ita uses the hubs-configtool library to flush configs to habitat.
• The hubs-configtool library flushes configs by executing the bio config apply command.
• That command is failing due to incorrect permissions on a public key file in /hab/cache/keys/.
• The public key file has incorrect permissions because it is deposited there when the janus-gateway package gets updated.
• We have infrastructure code that usually changes the permissions on these public key files, but that mechanism does not account for new public key files that are deposited as part of a package update.
• The janus-gateway package is unique because it was built recently with a private key file that is newer than the rest of the packages.
• Some older public key files exist in the /hab/cache/keys/ directory, and they have their permissions corrected properly. This is because they were deposited there during the AMI provisioning stage. (This might not be a fact, since I'm uncertain about when the AMI provisioning step occurs.)

Based on that information, here are some possible solutions to choose from:

• We re-build the janus-gateway package with a working key file.
• We re-build the AMI to include the new public key.
• We figure out a mechanism to update the permissions on new public key files when they are deposited by a package update.

We have deployed a fix for this issue to the beta stacks. Existing beta stacks will not be fixed automatically. You will have to either terminate all your EC2 instances, or destroy and re-create the stacks for the fix to take effect.

I have verified this issue and it's no longer reproducible. Now when editing the server settings fields and saving the changes we get a "Settings saved" pop-up message.

I think we can mark this as closed. The fix involved re-deploying the janus-gateway (dialog) package with a proper key file, so there wasn't a code change involved. Feel free to reopen if needed.
