Transport error: { type: 'socket' }

[reflash]

Describe the bug Running with 5.3.0 version - getting the error:

Transport error: { type: 'socket' }

This code has worked previously, so not sure what's the issue now

Code example

await this.mtProtoClient.call('auth.importBotAuthorization', {
    bot_auth_token: token,
})

Expected behavior Call is finished successfully

Context:

• Library version: 5.3.0
• Node version (if node environment): 12.22.1

@reflash do you have any progress with it? Some time ago tried to use it for PoW and got same error, but hadn't time to check where's the real problem
