Lets-Encrypt free SSL/TLS server for IIS10

I'm seeking urgent maintenance for my IIS server (Win2019). For free SSL certificates we're using Lets-Encrypt v.2.2.9.1701 [[login to view URL]] Not access allowed via AnyDesk (or Teamviewer) Main task: - create a batch file (.bat or .vbs or .ps1) to install certificate for new domain added (if any), - create a batch file (or the same file) to update certificate exipring or expired. About certificate renew, sometimes there is an issue (expecially if certificate is expired). See attachment log: "[login to view URL]" is my domain but there is an Authorization issues (https worked till 1 hour before, when certificate was not expired) Low budget available. NO placeholder: put you real offer.
