Can't connect to lumen.abda.nl

[tlhsa]

I'm trying to connect IDA to Lumen through socat

I have hexrays.crt in C:\lumen, and I'm running this command:

C:\lumen>socat -s -dd tcp4-listen:1234,fork,reuseaddr openssl:lumen.abda.nl:1235,cafile=hexrays.crt

I launched IDA with these environment variables:

set LUMINA_PRIMARY=guest:guest@localhost:1234
set LUMINA_PRIMARY_TLS=false

However, when I click "Pull all", IDA prints this error:

lumina: recv: An existing connection was forcibly closed by the remote host.
Command "LuminaPullAllMds" failed

At the same time, socat logs this:

2026/05/28 00:48:47 socat[10968] E connect(5, AF=2 129.159.136.126:1235, 16): Connection refused
2026/05/28 00:48:47 socat[7464] W waitpid(): child 10968 exited with status 255

Could you help me figure out what is wrong? Is the Lumen server down right now, or am I missing something in my setup?
