[ErSauravAdhikari]

Can we make it so that instead of crashing down, we use a different account for same request

[ErSauravAdhikari]

What might have happened was in a pool of accounts, each account is linked to a proxy and some proxies may end up not working (temporarily).

It will work at a later date, we can ignore this account for a while, and try with different account.

[ErSauravAdhikari]

I can add the retry mechanism client side, but I won't have access to which account was being used.

[ErSauravAdhikari]

If I did then I could have a retry logic to change the proxy by assigning a failover proxy for this.
