login does not continue past /signin

[frank1210]

Describe the bug
After successful login website goes back to /signin. Same behaviour described in #85

Docker config

docker create \
    --name subspace \
    --restart always \
    --network host \
    --cap-add NET_ADMIN \
    --volume /data:/data \
    --env SUBSPACE_HTTP_HOST=subspace.dev.xxxx.com \
    --env SUBSPACE_LETSENCRYPT=0 \
    --env SUBSPACE_HTTP_ADDR=":80" \
    subspacecommunity/subspace:amd64-v1.5.0

We are using image amd64-v1.5.0 as suggested in #193

Additional context
From logs i was able to retrieve the following warning:
WARN[0341] auth: sign in required

Browser url and SUBSPACE_HTTP_HOST are matching.

[rikki]

set SUBSPACE_HTTP_INSECURE=true

[pashkasan]

have the same problem, even with SUBSPACE_HTTP_INSECURE=true, but working by specifing server ip SUBSPACE_HTTP_HOST='1.2.3.4' and access admin interface by server ip
