I can't connect to my Jira site using the Tempo Mobile for Server app for Android. I get error "Jira Server Url is incorrect". No problems with iPhone.

Most of the time this is due to an SSL Certificate issue. Please do an online SSL check to verify if this is the case. For example, you can use https://www.sslshopper.com/ssl-checker.html to check. If you are getting errors or warnings saying something like "The certificate is not trusted in all web browsers", it may be necessary to update the root certificate on the Server to allow connections from various clients, as each Android phone manufacturer has its own customized system and browser.
