Pico 2W MbedTLS LwIP Crt verification fails on Supabase POST
13:38 17 Jan 2026

Issues with TLS Requests from Pico2W to a supabase project. TLS verify etc. works, because to another api it works just fine. But for the god of love, I can't get supabase to function. I used all kinds of certs, what openssl gives me, what supabase gives me in their database settings, supabase.com, R13 (the root). WE1 rooot etc.

I don't know how I should debug it, all I know is I get the expired error, but I made sure the time() is set correctly to this date using sntp, AON and setting it manually.

If anyone knows where I can find a solution that would be AWESOME.

Again: I am pretty sure it is specifically an issue with supabase
