SSL error for query_staking_summary

Discussed in #397

^{Originally posted by lars20070 July 2, 2024}
I try to retrieve the staked amount of a specific Axelar address with query_staking_summary as discussed in the docu. All gRPC endpoints listed in the chain registry fail with the same SSL error below.

Handshake failed with fatal error SSL_ERROR_SSL: error:100000f7:SSL routines:OPENSSL_internal:WRONG_VERSION_NUMBER.

Back a few months, I was able to connect to at least one of the endpoints. Now all of them fail as above.

Similar problems have been reported here. But I am unsure how further to debug.

Here a minimal example. None of the gRPC clients works.

from cosmpy.aerial.client import LedgerClient, NetworkConfig

# https://www.mintscan.io/axelar/address/axelar13s44uvtzf578zjze9eqeh0mnemj60pwn8slx2w
address = "axelar13s44uvtzf578zjze9eqeh0mnemj60pwn8slx2w"
# https://github.com/cosmos/chain-registry/blob/master/axelar/chain.json#L339
network_config = NetworkConfig(
    chain_id="axelar-dojo-1",
    url="grpc+https://grpc-axelar-ia.cosmosia.notional.ventures:443",
    fee_minimum_gas_price=1,
    fee_denomination="uaxl",
    staking_denomination="uaxl",
)
client = LedgerClient(network_config)
balance = client.query_bank_balance(address, "uaxl")
print(balance)
