Multiple error messages; mining does not work

[torusta]

When running the miner I first got these issues after about 5-10min run time

"There was a problem retrieving the KOIN balance."

"There was a problem retrieving the Ether balance."

As far as I can see I got everything set up correctly. Funding and recipient addresses are different.

After restarting the miner I am sometimes getting these additional error messages

"Failed to retrieve the start time from the token mining contract."

"Could not retrieve the PoW height."

In short, mining for me does not work currently

[Phispire]

Ditto. Tried to stop the miner but couldn’t, just kept throwing PoW height errors. Restarted, but don’t think it’s working.

Yep, I have same exact errors running on Windows 10 pro

[tandarae]

Same here. Windows 10. Mining starts then get these messages and stops.

• could not retrieve the PoW height
• problem retrieving the KOIN balance

Also got this once: Failed to check for transaction receipt: {“data”: null}

try changing your endpoint to http://mining.koinos.io/ I am trying it now and so far so good

We have noticed issues with the default endpoint. Try what @followbtcnews recommands; we set up an endpoint that seems to work better: http://mining.koinos.io

Please dont set frequency at 240 , you will go thru your eth paying gas fees very very fast. try between 1-24 for first few days

Exact same issues as OP and others. Will try using http://mining.koinos.io as others have suggested. Thanks!

after setting it to http://mining.koinos.io it ran for about 90 mins before giving me another error (ether balance). Has anyone else had success with switching the endpoint?

[drov0]

Getting "there was a problem retrieving the ether balance" on http://mining.koinos.io as well.

Can you use multiple miners on the same address ?

@drov0, @aaedx open a free account in https://infura.io/ and you get a wss:// endpoint with 100,000 requests for 24H no issue since i used it.

suggestion from lazydba247. creating account in https://infura.io/ works for me. Thanks.

Same here. Windows 10. Mining starts then get these messages and stops.

• could not retrieve the PoW height
• problem retrieving the KOIN balance

Also got this once: Failed to check for transaction receipt: {“data”: null}

I also got the transaction receipt error, but it seems it works ok after clicking "close"

[torusta]

The miner seems to work for me now; I only changed the endpoint to http://mining.koinos.io

But otherwise I will try what @lazydba247 suggested

Thanks for the engagement everyone
