Sitecore XP 10.3 - Some installation errors which i encountered for the first time

Hi Team,

This one will be very quick blog post around some of the issues i encountered during Sitecore 10.3 installation, Specially around SOLR

I have not got these issues in previous version and these were something new i encountered so drafting a quick post around it if it helps some of you save some time.

Also surprisingly, did not get this in error in later versions too like 10.4 

Below are the errors which i encountered 

1) Certificate Chain Was Issued by an Authority That is Not Trusted 

I never had this issue before, As generating certificate is backed in the script, but i still got this, so did little research around it and i found some Stack Exchange discussion, but i followed the same steps and it got resolved for me too, Though they are for older versions

Basically, I had to modify xconnect-xp0.json file, Search "InvokeSqlcmd" in it add "TrustServerCertificate": true to its "Params" property. You will find multiple matches for "InvokeSqlCmd", Do the same change for all of it.

2) Unable to connect to a remote server

Another one, which i was getting was unable to connect to a remote server, Well my internet was working fine, everything was ok, But was again not sure why it is not able to connect to SOLR to download the SOLR package for installation

What worked for me was

I turned off firewall security just for this installation and it worked, there could be better ways, but this worked for me and i was able to install it successfully 

You can tryother alternatives given here

Thank you
