SedonaWeb2.0 is a part of SedonaAPI2.0. Aka SedonaCloud (the name for both API2.0 and Web2.0; NOT to be confused with cloud hosted customers). IT installs and makes sure the API endpoint is able to connect to databases. Implementations handles SW 2.0 setup against an installed API endpoint. When you see SedonaWeb has "SedonaCloud version #" that's actually the same endpoint IT deployed. IT is currently cleared to deploy non-QA builds of SedonaCloud (up to version 1.15.1.1 currently). Any version of SedonaCloud should work with any 6.1 install as well as 5.7.0.99 with a patch as far as IT knows. Questions on higher versions of the API than IT installs should go to development as we should not have been the ones to push that update. Questions on SW 2.0 in cases like this where the site is reachable but there is some other issue go to support/implementations or possibly escalate to development.
