Fixing: Sitecore 9 installer unable to connect to Solr server, while it is available

Recently tried to reinstall Sitecore 9.0 update 1 and got the following message:

"Request failed: Unable to connect to remote server" (and the URL which is default https://localhost:8389/solr)


Opening Solr in browser went well, and there were no existing cores that could prevent the installation. Weird...


After experiments, I found out that was an antivirus preventing such requests. Disabling it allowed cores to be installed well and thу rest of install script succeeded.
