Wallets unable to connect to ABCore full node

[nagarajhubli]

I am using v0.73 of ABCore, but the wallets are unable to connect to the full node, tried with Blockstream Green Wallet, as well as with Bitcoin Lightning Wallet, both the wallets are unable to connect to the ABCore.

I am running ABCore on OnePlus One phone, and I have the wallets on Redmi Note 5 phone. I have installed Orbot, and enabled Green Wallet and Bitcoin Lightning Wallet as Tor-Enabled Apps.

Pruning is enabled, and has been set to 1000 MB

Is there any setting I need to do in bitcoin.conf file to make this work? Thanks.
