JIRA Testlink integrate

Trying to integrate JIRA v7.3.2 with testlink 1.9.13 but failed all the time

I use jira rest api in the Issue Tracker Management due to the soap is removed above jira 6.4.


While, I open the test execution page, It’s blank enter image description here

When I debug the process and enter JIRA rest api url http://MY-JIRA-CLOUD-NET:PORT/rest/api/latest/ | JIRA it return 404 error or blank page. Anyone have ever occur this issue?
