How to connect retool self-hosted and jira Data Center

[Robert]

Hi,
I want to connect retool and jira data center with OAuth 2.0, but it doesn't work.
Do you have any advice? I have run out of ideas.

What I have tried.
The Credantials Cliend id and Client Secret were generated with the OAUTH callback URL,
I copied this information into Retool.
I have set the basic URL https://my.domain.com ,
the Authorization URL https://my.domain.com/rest/oauth2/latest/authorize ,
Access token https://my.domain.com/rest/oauth2/latest/token and Scope is write:jira-user in retool.
When I test the connection, the circle of death appears and than Error 500.
Thanks a lot

HI @Robert 

Overall 500 error usually mean that is related to server-side.. I would stat by checking request route from one place to another. 

You can use basic authentication connection to see if we should focus on network or specific OAuth configuration. That kind of problems might be also any caused by rate limiting or proxies. Using Postman and simulating the traffic might be also handy. 

If possible it is good to verify the logs and see for any specific clues.
