I’m one of the upstream OpenConnect developers. Thanks for bringing this
to our attention. This is one of a seemingly-endless stream of issues
(e.g. https://gitlab.com/openconnect/openconnect/-/issues/211) that
OpenConnect users have encountered as a result of distros’ recent mania
for enforcing “minimum TLS security levels” on a system-wide level.

It’s a frustrating situation for OpenConnect because users often have to
connect to ancient unpatched VPNs to do their work, can’t do anything
about the server configuration, and have no real expectation of
“security” anyway.

> My feeling is that curl should set the SSL option when -k is used.
openconnect itself sets this option already, it was fixed in commit
c8dcf10

If you replace the cURL invocation in the CSD/Trojan script with…

```
OPENSSL_CONF=/dev/null curl <usual options>
```

… does this make it work? (For some hints about how/why it should work,
start with
https://gitlab.com/openconnect/openconnect/-/commit/7e862f2f0352409357fa7a4762481fde49909eb8#406e031b8824ea26ae0bf4d7579a1d89e3fb5906)
