Proxy only loads 4 servers mapped directly

[Kein]

Here is what I have in config

#DNSCrypt direct
[static.'server1']
stamp = 'sdns://sadasdasda'
[static.'server2']
stamp = 'sdns://adasdas'
[static.'server3']
stamp = 'sdns://asdasda'
[static.'server4]
stamp = 'sdns://asdsadasd'
[static.'server5']
stamp = 'sdns://dfgdfgdfg'
[static.'server6']
stamp = 'sdns://adssadasdada'
[static.'server7']
stamp = 'sdns://dgfdgdfgdf'

server_names = ['server1', 'server2', 'server3', 'server4', 'server5', 'server6', 'server7']

This is what I get in log at startup:

[2021-08-01 10:39:37] [NOTICE] [server1] OK (DNSCrypt) - rtt: 77ms
[2021-08-01 10:39:37] [INFO] [server2] the key validity period for this server is excessively long (1311 days), significantly reducing reliability and forward security.

[2021-08-01 10:39:37] [NOTICE] dnscrypt-proxy is ready - live servers: 4 

I've pinged all the servers and they all respond to my queries - so they are reachable and this is not a network issue. However, DNScrypt can only process 4 of them.

Check these servers individually, either by configuring only one of them at a time or with a client such as doggo.

The ping command doesn't check if a DNS server is accessible.

Okay sure, will do, but why wouldnt it even output a log message that specific server failed to respond or unavailable or anything? It literally does not even mention any of them like they dont exist, even with most verbose logging setup? Is this sdns string parse error? dnscrypt server port not responding/open? It should not be a guess work.

P.S. I've tested the IP:PORT combos via netcat and they are all fine and reachable. DOGGo shows only one of them is not responding and the tool hangs on another one with expired cert but DNScrypt proxy has no issues with that one so I will assume tool is wonky
