BTCPayServer attempting to connect to Eclair using TLS

Describe the bug When creating an invoice using the /invoices/create page it’s no longer possible to use BTC currency. I remember this being possible in the past, so I’m filling this as a bug.

To Reproduce the bug Steps to reproduce the reported bug:

1. Go to “Invoices” page
2. Click on “Create an invoice”
3. Fill amount (e.g. 0.0001, doesn’t matter)
4. Enter “BTC” (without quotes) into the “Currency” field
5. Click Create

Expected behavior

An invoice is created with specified amount in BTC.

(Ideally SAT would be possible too, but that’d be a feature request, not a bug.)

I just realized I forgot to switch store in the latter tests - after 1.3.2 and the previous issue magically fixed itself. Closing now and if it ever repeats I’ll probably open a new one. Sorry for the noise.

It seems that in #3065 we’ll be able to have better error messages so we can see what an underlaying error of this issue may be. Let’s wait for 1.3.2 and fix this afterwards.
