Hotfixes to address issues are:
- Apply hotfix CP_8.5.0.12222 to address the Content Porter connectivity issue. 
- Apply hotfix TB_8.5.0.12223 to address the Template Builder connectivity issue.
- Apply hotfix CM_8.5.0.12224  to address the TCMUploadAssembly connectivity issue. 
- Apply hotfix CM_8.5.0.15956 to address the SOLR search request issue.
- Apply hotfix CM_8.5.0.12074 to address the Visio Workflow Designer issue.

Note that TLS 1.2 is enabled by default for Sites 9.0+ for Template Builder, Content Porter, Solr, and tcmuploadassembly.  It is still required to configure the underlying O/S for TLS 1.2 as discussed in KB article  For Web 8.5, configuring CM and CD environment to only allow security protocol TLS 1.2

See below KB article to download hotfixes.
Where can I find hotfixes for SDL Tridion/Web?
