note the above does not prompt me for creds

same creds for vcsa?
in VCSA i have configured Identity sources to point to my windows domain, my ID is full admin everywhere, no fw blocking
srm plugin is fully connected to/in both sites (SRM 8.2 and replication 8.2)
DNS is all good

new env. so i only have 1 Vm replicating,, but in the web plugin i can test failover, modify all settings etc., that all looks good

from what i have read/understand just connect-srm server should work, but even when i try adding in the srm appliance IP

note this variation asks me for creds, i have tried my windows ID, and the vcsa and srm local internal IDs (root),

and this error is slightly different from above

yup tried that

and this error is occurring at both sites vcenters/srm, 2 separate windows servers that i am running the ps command from
one in each site, get same results to each individual vcenter/srm

anything else to try?

installed versions of what i have

vcenter 6.7u2a appliance(both sites)

srm 8.2 (appliance) both sites (replication 8.2 as well both sites)

windows 2012r2 (fully up to date)

I had submitted a comment/feedback from inside the SRM plugin last week (and had not heard back) until late last night from vmware
This is the "fix" (which i have confirmed as working in both sites)

“connect-srmserver -Port 443”

The reason is there is a change in the port used with the SRM appliance.

my install is default install (not sure what port it was trying)
