Microsoft Flow Connection to Jira Server

[Ian]

Hello,

I know that to establish a connection to Flow it requires an API token. I learned that there is no native way to generate an API token in Jira server. I decided to use a 3rd party plug in for Jira server to generate an API token.

My connection to Microsoft Flow has worked really well for one signle day after which with no given error it simply doesn't work. 

I learned that Flow and Jira dropped support for connection to server but it doesn't explain why that first day everything worked.

Any suggestions?
