timeout calling estimateGas on Polygon zkEVM using Rabby

[omnifient]

Hi team, strange behaviour.

When using rabby, and making a call to estimateGas, it fails with http2: timeout awaiting response headers.
The same call works with Metamask, as well as with a local script.

This points to an incompatibility between Rabby and Polygon zkEVM - reaching out to you as this is mainly happening when using Rabby.

Just wanted to 👍 this. We're seeing users face this issue on Dolomite!

How can I reproduce your issue?
Can you try to copy curl directly here?

You can reproduce it by doing the following:

• Visit app.dolomite.io
• Select Polygon zkEVM network on the top toolbar
• Press the Swap button on the Balances page to swap an asset you have deposited. I chose ETH --> MATIC
• Attempt to submit the Swap and you can see the network request that fails as well as the error logged to the console, as shown below:
  
• Key thing is that all gas estimation calls fail

This works in my side

The site sets a default gas limit if it fails. You'll need to check the dev console while submitting to see if it works or not (like in the screen shot I shared)

[coreycaplan3]

should be fixed now

I'm getting this error now when testing

[vvvvvv1vvvvvv]

I tried other rpc but no one works with this call

[omnifient]

we're almost there, this is what I got

• did NOT get the same error as Corey
• no errors in the console

[omnifient]

hi @vvvvvv1vvvvvv any thoughts on this?

[coreycaplan3]

@vvvvvv1vvvvvv bumping this as well!

[vvvvvv1vvvvvv]

should be fixed soon with our self-host rpc endpoint, this timeout caused by calling remote rpc endpoint
