Vercel SSL issue on old android api 24 and below

Help
1

I’m using nextjs as my backend which is in vercel right now and my app is connecting to it with api request, everything works on android 25+ but my problem is that it does not work properly when tested on android 23/24, the lowest version my app supports is android 23 but I keep getting the handshake error

chatgpt keeps pointing that it might be a vercel problem and that the ssl it uses is not trusted and will not work on old android devices? is there a way I can fix this on vercel?

Here’s the full error if it helps…

I/flutter ( 6037): HandshakeException: Handshake error in client (OS Error: 
I/flutter ( 6037): 	CERTIFICATE_VERIFY_FAILED: unable to get local issuer certificate

Hi,

It looks like your dev environment isn’t trusting Letsencrypt certificate for some reason. Do you use Flutter: Handshake error in client (OS Error: CERTIFICATE_VERIFY_FAILED: unable to get local issuer certificate(handshake.cc:354)) · Issue #50699 · flutter/flutter · GitHub?

Unfortunately, there is nothing much we can do. You need to check with Android SDK support team to find more information on this.
