@cipig could you please check if mm2 returns/logs addresses of slow RPC nodes?

updated 2 nodes to this branch and waiting for timeouts
in the meantime i found this too rpc:239] ERROR RPC error response: rpc:174] dispatcher_legacy:155] lp_ordermatch:3825] maker_swap:1600] result:1897] eth:2422] Transport error: RPC error: Error { code: ServerError(-32000), message: "insufficient funds for transfer", data: None }
looks like it is related to one of the RPC nodes returning 0 balance (or something totally weird) for the coin, although my_balance shows 10.3199111365536
should the PR cover this too?
EDIT: happens on setpricecall

It's hard to understand what node's result we should consider as "truth" in this case. I think it's out of this PR scope - switching between addresses should happen in case of network errors.

ok, catched first errors, they now show up like this

27 11:10:53, wio:72] drive03 receiver is dropped
27 11:10:55, wio:72] drive03 receiver is dropped
27 11:10:55, wio:72] drive03 receiver is dropped
27 11:10:59, wio:72] drive03 receiver is dropped

i know it's related to Polygon coins and to which of them, but not which server it is

maybe it's related to my own timeouts (how long the bot waits for response from mm2 on certain calls)
i recently reduced those to 10s... now set them back to 30s
what is the timeout on mm2 side for requests to RPC nodes? if i use a lower timeout then that, i will never catch the errors from mm2 i guess

saw this error to gas_station_url

27 14:12:40, rpc:239] ERROR RPC error response: rpc:174] dispatcher_legacy:155] lp_ordermatch:3825] maker_swap:1600] result:1897] result:1897] eth:317] Transport error: Transport 'https://gasstation-mainnet.matic.network' error: Gas price request failed with status code 502 Bad Gateway

it contains the URL
what about the second line with invalid type?

Hmm, since a request to some RPC node has not been timed out, you didn't get an error from mm2. I'll try to add a log message on the timeout.

what is the timeout on mm2 side for requests to RPC nodes?

60 seconds. As you said before, you may not receive an error from mm2 due to your own timeouts. I'll add a log message anyway to catch the error.
