getPastEvents Connection error

I wrote the code exactly the same one with example code.
And it works perfectly before few days ago.
But now I get the connection error most of the time when I try to call it.

contract.getPastEvents('Transfer', {
fromBlock: 0,
toBlock: "latest",
filter: {
isError: 0,
txreceipt_status: 1,
[type]: toAddress
}
}, function(error, events){
});

Very simple code, worked well just few days ago.
I still can get the returned value from time to time, chances like about 1 out of 10.
So I assume that it's not the code issue.
And it also takes few seconds to get it.

Except for getPastEvents, everything works well such as check balance, sending transaction.
So I assume that there is no problem with global settings.

Any assumption for this problem?

Which version do you have installed ? Days ago a new release came out. Problematic for me, so I maintain the @beta.35.

[wowprojector]

It was @beta.34 and I updated it to @beta.35.
Still not working.

[wowprojector]

It is okay now without modifying anything. Is this reliable for real service?

[glemmaPaul]

Hey @wowprojector have you tried using @beta.36 already?

Can I also get your web3 provider info, is this a local geth node or something like infura service?

[wowprojector]

I have never tried @beta.36 yet. Now it is just fine with @beta.35.
I am using infura rinkeby. However when problem occured, I tried with every provider but none of them worked properly.

I think this PR #1966 will solve your issue. Web3 has some problems with the socket connection.

This got fixed with the new WebsocketProvider.
