The error is caused by that Bitbucket rejects the application links polling request from Jira. The most common possible root causes are:

1. The request URL is too long, the return code normally is 414.
2. The header is too large, the return code normally is 400.
3. Some specific settings for plugin.dev-summary.

How to solve this issue? It really depends on how you set it up. Take a typical architecture for example: Jira -> Nginx -> Bitbucket. The troubleshooting steps should be:

1. Check your Nginx to confirm whether it rejects the request from Jira. If yes, then tune the client_header_buffer_size and large_client_header_buffers parameters to fit your needs.
2. If Nginx does not reject the request, then the problem should be in the upstream – Bitbucket/Tomcat. How to confirm that? Check the Nginx errror log, you should see something like: [error] 24#24: *46774189 readv() failed (104: Connection reset by peer) while reading upstream, client: xxx.xxx.xxx.xxx, server: xxx.xxx.xxx, request: “GET /rest/remote-link-aggregation/latest/aggregation?globalId=xxx-xxxx&….
3. Check the server.max-http-header-size in the bitbucket.properties, update it to a larger value to match your incoming requests.
4. If none of them solved your problem, then you probably need to tune the plugin.dev-summary.xxx parameter. Check details here: https://confluence.atlassian.com/bitbucketserver059/bitbucket-server-config-properties-949255485.html
