New SIA Errors and resolutions notes

I decided to add these notes since I faced these a couple of times and both times what I did to resolve seemed to work for me. So, good if it helps someone in future. Although this is very specific to your local installation, as a first step, check your internet connection/bandwidth since it could be one of those days when the internet provider is flaky.

Anyway, these errors happened while using Sitecore Install Assistant(SIA) to install Sitecore 10.4.0 instance along with SXA:

1. I was getting the following error as part of installing Solr 8.11.2 instance -

[------------------------ DownloadSolr : DownloadFile ------------------------]

[DownloadSolr]:[Download] http://archive.apache.org/dist/lucene/solr/8.11.2/solr-8.11.2.zip => C:\Users\conta\AppData\Local\Temp\solr.zip

Error downloading http://archive.apache.org/dist/lucene/solr/8.11.2/solr-8.11.2.zip: Unable to read data from the transport connection: An established connection was aborted by the software in your host machine.

In the Virus and threat protection, I switched off Real-time protection and that resolved the issue when I executed the installer next time.

2. This one happened as part of setting up SXA in the far-end of the installation -

[---------------- Solr_CreateCores [1] : ManageSolrCore ----------------------]

[Solr_CreateCores [1]]:[Requesting] https://localhost:8764/solr

This happens as part of the optional SXA installation. I'm unsure if my internet connection is to be blamed for this.  However, I couldn't suspect the connection since it failed only in this step, time and again, although there are so many places in the installation process where downloads happen and they were successful.  Also, my solr url was reachable so, that was eliminated from the suspect list. Also, my machine seemed low on resources so, my hunch was to give the related steps more time. Nevertheless, I increased the PostDelay duration in sxa-solr.json from 8000 by adding an extra zero and it seemed to work fine in the next run -
