Describe the bug

After creating a stream with Forward Host IPv6, the stream ist always offline.

Nginx Proxy Manager Version

v2.9.9

To Reproduce
Steps to reproduce the behavior:

1. Go to Hosts --> Streams
2. Click on Add Stream
3. Insert Incoming Port, Forward Host IPv6, Forward Port and save
4. Status is always Offline

Expected behavior

Stream should be online.

Screenshots

Operating System

Debian 10

Additional context

The IPv6 Host is reachable (Ping) over the IP. When I create a Proxyhost with this IPv6 IP the state is online but I get a 500 Internal Server Error. I have seen in the log, that there are no brackets infront and at the end of the IP. So the Port is directly behind the IP. Example: invalid port in upstream "fd00::aaaa:bbbb:cccc:dddd:80"
So I think this could be also the problem with the stream.
