403 Client Error

[krau5]

I have the following line, where I am getting the usdt contract by its address

self._contract: Contract = self._tron_client.get_contract(self._network_data.usdt_token_address)

But when I run the code, I receive

File "/root/app/utils/tron_client.py", line 28, in __init__
  self._contract: Contract = self._tron_client.get_contract(self._network_data.usdt_token_address)
File "/root/venv/lib/python3.10/site-packages/tronpy/tron.py", line 966, in get_contract
  info = self.provider.make_request("wallet/getcontract", {"value": addr, "visible": True})
File "/root/venv/lib/python3.10/site-packages/tronpy/providers/http.py", line 89, in make_request
  resp.raise_for_status()
File "/root/venv/lib/python3.10/site-packages/requests/models.py", line 1021, in raise_for_status
  raise HTTPError(http_error_msg, response=self)
requests.exceptions.HTTPError: 403 Client Error: Forbidden for url: https://api.trongrid.io/wallet/getcontract

The API key for TronGrid provider is alright ( it works locally ), but when I try to run the same code on the server - it fails. The only difference is python version ( 3.10 on server & 3.11 locally ), but could it even raise such a problem?

What should I do?

[krau5]

I've updated the python version. It's not about the python. Why does the code locally and on server executes differently, although it's the same ( I literally cloned the repo and copied the configuration )

[MrNaif2018]

Hmm, Forbidden usually means trongrid bans ip? Check if maybe it's cloudflare doing it's stuff You can test with ankr RPCs too

[krau5]

Won't it say on trongrid that the api key has blocked some requests if it banned the ip? By the way, which cloudflare are you talking about?

[krau5]

I've just created a new API key, no changes, same error + TronGrid does not give any information if the request using exact API key was blocked or sth

[MrNaif2018]

Trongrid might be behind cloudflare and it might be banning your server. Usually by checking response headers you can know

[krau5]

But the error is from the tronpy library. It's not the part of my code which fails and I can get the response directly

[krau5]

Specifically on this line

File "/root/venv/lib/python3.11/site-packages/tronpy/tron.py", line 966, in get_contract
  info = self.provider.make_request("wallet/getcontract", {"value": addr, "visible": True})

[MrNaif2018]

But the error is from the tronpy library

Not it is not, it is from sending the request to trongrid Try with another rpc like https://www.ankr.com/rpc/tron

[krau5]

Uhm... but it literally says venv/lib/python3.11/site-packages/tronpy/tron.py in line

info = self.provider.make_request("wallet/getcontract", {"value": addr, "visible": True})

I'll have a look at that rpc, although I do not understand how it's related to the issue

[MrNaif2018]

Because it sends an internet request, and status code forbidden means server (the rpc, not the library) blocked your request for some reason

[krau5]

So I can somehow pass the specified rpc inside the library or should I change the approach in the code if so?

[krau5]

I've made a contact with trongrid, they did not have an explanation either, so I've moved a server from one location to another and it works fine now

[krau5]

Weird thing, tbh

[MrNaif2018]

Yeah, as I've told you could switch from trongrid to something better or investiate why cloudflare blocks your server. Glad you got it resolved
