An error occurred while trying to retrieve additional information from the Solr server

Downloading the zip should be possible when you turn off the auto-detection of the Solr version in the server settings or if you use drush to get the zip.

Obviously you can't establish a connection. Which Solr version are you using?

I have tried both Solr 8 and Solr 9 ,the issue exists on both.

Next I tried the Solr 9 and I took this error message:

An error occurred while trying to retrieve additional information from the Solr server: Solr endpoint http://localhost:8983/ not found (code: 404, body:

Searching for Solr?
You must type the correct path.
Solr will respond.

, message: Solr HTTP error: OK (404)

Searching for Solr?
You must type the correct path.
Solr will respond.

).

Here is an image of my Solr settings attached:

Obviously, the Solr server responds. Check the Solr logs for issues.

Hello,
I have been getting the same issue with connector Solr Cloud.
I have checked the logs on solr, nothing in particular appears that might explain the issue.

The server connection is ok on Drupal side, i can upload the configset and do reload of the collection but i keep getting:

An error occurred while trying to retrieve additional information from the Solr server: Solr endpoint http://solr-solrcloud-headless.solr.svc.cluster.local:8983/ not found (code: 404, body:

).

can you assist in this please?

Hello,
I'm facing a similar issue with SolrCloud as connector.
On the server, we do not see any errors in logs, but on Drupal, i'm having same issue.

Tried on both Drupal 9, 10

I am using Postgresql, are you also using Postgresql? I mean, could this be the issue?
