I think this should be the second question. The first quesion is: What
are the actual symptoms?
In this case we have a relatively clear error message which was
obviously[2] sent by the server. So anything else must[1] be consistent
with this error message (and the fact that we were able to get this
error message in the first place).
So it can't[1] be TLS, because if you can't establish a connection, the
server can't send an error message.
The message also says "internal server error", and this is not something
a client should be able to provoke. So it's unlikely to be anything on
the client side.
What's left is that there was a change or operational error on the
server side, so further analysis must be conducted there.

[1] Take absolute assertions like this with a grain of salt. There are
always misleading error messages, weird edge cases, etc. But
consider those only after ruling out everything else.
[2] What may be obvious to one person is of course not necessarily
obvious to another.
