[jira] [Comment Edited] (IGNITE-25412) Fix flaky tests in GridTcpCommunicationInverseConnectionEstablishingTest
[ https://issues.apache.org/jira/browse/IGNITE-25412?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17954916#comment-17954916 ]

------------------------------------------------------------------
Root Cause:
The issue occurred because on the agents, `/etc/resolv.conf` needed to be a symlink to `/run/systemd/resolve/stub-resolv.conf`, but it was a regular file instead.
This caused tests failed on timeout due to slow DNS resolution for "unresolvedHost" (28 seconds).
Resolution:
After fixing /etc/resolv.conf to be a proper symlink, all tests passed successfully.
