Couchbase 6.5 community Version Indexes are disappeared

My Couch base Indexes are disappeared this happened after i restarted the couchbase server on my windows machine. i checked the path C:\Program Files\Couchbase6.5\Server\var\lib\couchbase\data@2i
and all the indexes are there in the folder but not in the web console.

here is my indexer.logindexer.zip (136.0 KB)

Solved the issue after i restarted my PC . but would be nicer if anyone knows why this happened Thanks

Hi @muhammad_ibrahim, took a quick look at your logs.

Indexer was restarted at 2020-06-15T17:16:44. At this time, indexer could not listen on required port 9101, which lead to indexer being unavailable.

Did you start the Couchbase Server with a user that has enough permissions to create/access the network port ini question ?

The index list cannot be displayed on UI as the corresponding indexer service was not reachable - due to above mentioned port bind error. The UI typically shows a warning in the “Indexes” tab, bottom left corner in such cases.
