[SOLVED] ERROR: Can't verify SSL peers without knowing which Certificate Authorities to trust
I seem to have broken my install of Get_Iplayer as a result of relocating my User folder and I'm hoping that someone may be able to help me out.

The problem that I'm having is that get_iplayer is not downloading the schedule pages correctly. When refreshing the cache I get the following:

WARNING: Failed to download schedule page: http://www.bbc.co.uk/bbcalba/programmes/.../this_week

I've read on a previous post that this is associated with the requirement to use https: rather than http: and that obsolete Perl modules could give problems. Unfortunately I'm nowhere near well enough versed in Perl to be able to sort out what's going on. I've deleted and reinstalled multiple times (using HomBrew) but can't seem to get to a working configuration.

I've listed below information that will hopefully help with diagnosing my problem.

Operating System: Sierra 10.12.6
Get_Iplayer: 3.12-Homebrew

Hopefully someone can highlight what I'm doing wrong!

Thanks in advance.
This is a Homebrew installation problem - take it to their forum. We don't support that here. Technically, it's a macOS problem - there is a module missing in the system Perl - but it is up to Homebrew whether to provide the module or a workaround in the runtime environment. Users who have done a full manual installation on macOS (incl. updated versions of all Perl modules used by get_iplayer) should be OK, along with users on other platforms. Since this is a matter for Homebrew, this thread is closed - see forum rules.
Also: Without a full report, there is nothing we can say about your problem downloading schedule pages. I wouldn't necessarily expect it to be related to the missing Perl module that causes the SSL verification errors, but there is no way to know. If you want to pursue the issue, follow our instructions to create a proper problem report in a new thread.
Finally: Your problem downloading schedule pages may in fact stem from failed SSL verification if the Mojolicious module is also missing. Again, no way to know without a full report.
Even more finally: Users who performed a minimal manual installation (macOS system Perl + local library installation of Mojolicious and IO::Socket:SSL) will now also need to install the Mozilla::CA module in your local module library. Installation doc has been updated accordingly.

EDIT: Another workaround is to export PERL_LWP_SSL_VERIFY_HOSTNAME=0 in your shell environment before running get_iplayer to bypass SSL verification, but I can't recommend that to users. It's not necessary, anyway - just install Mozilla::CA.
