Lightning Address and LNURL does not work

[ChuckNorrison]

Iam running the LightningTipBot (v0.5) on my Raspiblitz (v1.8.0) based on LNBits (v0.9.4).

LNBits is forwarded to Clearnet on Port 443 (https). If a LightningTipBot user on Telegram go to /advanced, he gets shown the Lightning Address like [email protected] or a LNURL decoded as https://mydomain.org/.well-known/lnurlp/0x7fa3a123456cb7fa\

If try to make a Payment, errors are shown in LightningTipBot logs:

level=warning msg="[HandleLNURL] Error: Get "[https://mydomain.org/.well-known/lnurlp/0x7fa3a123456cb7fa](https://mydomain.org/.well-known/lnurlp/0x7fa3a123456cb7fa%5C)": socks connect tcp 127.0.0.1:9996->mydomain.org:443: dial tcp 127.0.0.1:9996: connect: connection refused"

I can not find a listening lnurl server on 9996 via netstat.
