Also try to update to version 5.0.13, everything updated fine, then try to update to version 5.1.3 and got the same error.

Please, help resolve the issue with upgrade Proget from 5.0.12 to 5.3.15 version. Run Inedo Hub but after some time got error. Tried to uninstall Proget and Inedo Hub (use this man https://docs.inedo.com/docs/desktophub/troubleshooting), but the same error.

Thanks, with version 2.2.5 all works fine.

@jjones said in Error create server role:

steps

Was installed new server with new DB, next was connected to Git Raft which contains "orchestrations", "scripts" and "roles" but roles does not appeared in Otter, only appeared in "Plans"-"Configuration" with prefix "R". Tried to create new role but got error, than removed roles from Git and removed from "Plans"-"Configuration" but got the same error.

Reinstall server from scratch, the same error.

After new install this exception always happens.

I updated server to 2.2.3 version, then stop all services and made backup database. Installed new Windows server 2019 and install Otter 2.2.3 using existing database. I use raft - TFS Git repository, on new server I deleted old raft and create ne one. To connect to Linux systems I use Private Key resource credentials it works fine.

Can not connect to Windows servers with WSMan endpoint. Try to use credentials FQDN and Netbios, result - exception.
