[BUG REPORT] Wallet shows 0 balance

[fredteumer]

Describe the bug After upgrading some regions to V2, the RPC connection to the POKT Network appears fragmented and

To Reproduce Steps to reproduce the behavior:

1. Go to https://wallet.pokt.network/
2. Click on Import
3. Login with your preferred method (private key or keyfile)
4. See that your previous balance is now 0

Expected behavior Instead, upon logging into the wallet it should show the correct balance as in when querying direct to the pokt blockchain.

Screenshots If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

• OS: any
• Region: appears to be isolated to V2 regions, but could be more widespread
• Browser(s): Any

Additional context This seems to be an issue related to the recent deployment of V2 Portal and the ability to process RPC on the POKT Network

We've isolated the issue that it is a middleware issue with V2. V2 has a strict parsing on JSON-RPC standard which is causing the non-JSON-RPC compliant Pocket Network calls to fail.

[fredteumer]

Issue was temporarily solved by rolling back V2. Waiting on patch to loosen JSON-RPC validations for the POKT network

[fredteumer]

Issue is solved in V2 with this PR: https://github.com/pokt-foundation/portal-middleware/pull/289. Closing this bug :bug:
