Peer Caching, unable to download from peer

[Siroj 2]

Our Setup:
- SCCM 1806 on Server 2016
- Clients are running Windows 10 1709 (about 25000 clients)
- Clients running corresponding SCCM client v5.00.8692.1008

We are trying to utilize Peer Caching but are unsuccessful in getting it to work. After a number of tries to connect to a peer, it uses the DP as last resort and successfully downloads the data (but not from a peer cache source).

We verified that firewall ports (8003, 8004) are opened at the source peer. We re-entered the NAA account info and successfully verified. For testing purposes we also granted full access rights to CCMCACHE folder to the NAA account

In SMSTS.log we see that the client has located a peer, tried to connect but failed. Some possible relevant LOG entries:
