Not able to search or install plugin from Atlassian Marketplace

[Ecomap Dev]

I have installed a Server edition of Jira but whenever I search for any app, it stuck with a loading icon.

Developer console throws following error

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://DOMAIN_NAME/rest/plugins/1.0/available/recent?q=Capture. (Reason: CORS preflight response did not succeed).

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://DOMAIN_NAME/rest/plugins/1.0/available/recent?q=Capture. (Reason: CORS request did not succeed).

What to do?

Also, when I tried to install already listed plugin, that is also throwing some error.

Hi Ecomap Dev,

Greetings for the day!

The UPM must be able connect to the Atlassian Marketplace website to perform a number of functions, such as checking for app updates and installing new apps.

Ensure that you have correctly set the base URL for the application.

Check whether a firewall is blocking UPM access to the Atlassian servers, for example, by attempting to ping the marketplace.atlassian.com server from the computer that hosts the Atlassian application.

Universal Plugin Manager needs access to:

• https://marketplace.atlassian.com
• https://marketplace-cdn.atlassian.com
  • Since IP addresses for a given domain can change over time, Atlassian recommends that you configure your firewall policy by hostname rather than by numeric IP address.

Please check below.

By default, UPM uses the proxy settings of the host application to connect to the Marketplace. If UPM cannot connect to the Marketplace server, you should verify the proxy configuration for the host application.

Most of the time issue get resolve after configuring an outbound proxy for jira.

Hope it will help you.

Thank you,

The things is if I don't search for any plugin, all the plugins are loading fine and even pagination is working properly.

Only Search function is effected.

Since it can load plugins and pagination is working, it can connect to the Atlassian Marketplace successfully but not only in case of Searching.

Why is it so?
