Trying to do a REST get using Jython but getting an SSLError.

The regular java way of doing it works.
>>> import java.net.URL as URL
>>> url = URL("https://jsonplaceholder.typicode.com/posts/1")
>>> conn = url.openConnection()
>>> conn.setRequestMethod("GET")
>>> conn.setRequestProperty("Accept", "application/json")
>>> conn.getResponseCode()
200
Why am I getting an SSLError when using requests? Do I need some further configuration to make it work?

I am using Celery with SQS as a broker and I am trying to renew my credentials "AWS_ACCESS_KEY_ID" and "AWS_SECRET_ACCESS_KEY", before they expire, the first time I run the task and the result is success, but after 15 minutes it expires although credentials have been renewed, the function to update credentials is as follows:
import os
import boto3
from celery import Celery
from kombu.utils.url import safequote
def update_aws_credentials():
role_info = {
'RoleArn': f"arn:aws:iam::{os.environ['AWS_ACCOUNT_NUMER']}:role/my_role_execution",
'RoleSessionName': 'roleExecution',
'DurationSeconds': 900
}
sts_client = boto3.client('sts', region_name='eu-central-1')
credentials = sts_client.assume_role(**role_info)
aws_access_key_id = credentials["Credentials"]['AccessKeyId']
aws_secret_access_key = credentials["Credentials"]['SecretAccessKey']
aws_session_token = credentials["Credentials"]["SessionToken"]
os.environ["AWS_ACCESS_KEY_ID"] = aws_access_key_id
os.environ["AWS_SECRET_ACCESS_KEY"] = aws_secret_access_key
os.environ["AWS_DEFAULT_REGION"] = 'eu-central-1'
os.environ["AWS_SESSION_TOKEN"] = aws_session_token
return aws_access_key_id, aws_secret_access_key
def get_celery(aws_access_key_id, aws_secret_access_key):
broker = f"sqs://{safequote(aws_access_key_id)}:{safequote(aws_secret_access_key)}#"
backend = 'redis://redis-service:6379/0'
celery = Celery(f"my_task", broker=broker, backend=backend)
celery.conf["broker_transport_options"] = {
'polling_interval': 30,
'region': 'eu-central-1',
'predefined_queues': {
f"my_queue": {
'url': f"https://sqs.eu-central-1.amazonaws.com/{os.environ['AWS_ACCOUNT_NUMER']}/my_queue"
}
}
}
celery.conf["task_default_queue"] = f"my_queue"
return celery
def refresh_sqs_credentials():
access, secret = update_aws_credentials()
return get_celery(access, secret)
Running refresh_sqs_credentials, new credentials are created:
celery = worker.refresh_sqs_credentials()
And then I run my task with celery:
task = celery.send_task('my_task.code_of_my_task', args=[content], task_id=task_id)
All tasks that I run before 15 minutes finish successfully, but after 15 minutes the error is the following:

I'm new to anaconda so I don't know what else to provide. Please leave a comment if I need to anything and I will add it right away. Thanks.
Try to add this path to your environment variable:
..\Anaconda3
..\Anaconda3\scripts
..\Anaconda3\Library\bin
You might need to restart windows after set up environment path
s3fs seems to fail from time to time when reading from an S3 bucket using an AWS Lambda function within a VPN. I am using s3fs==0.4.0 and pandas==1.0.1.

s3fs.S3FileSystem.read_timeout = 1800

Has someone faced this same issue? Why would it fail only sometimes? Is there a s3fs configuration that could help for this specific issue?
Actually there was no problem at all with s3fs. Seems like we were using a Lambda function with two Subnets within the VPC and one was working normally but the other one wasn't allowed to access S3 resources, therefore when a Lambda was spawned using the second network it wouldn't be able to connect at all.
Fixing this issue was as easy as removing the second subnet.
You could also use boto3 which is supported by AWS, in order to get json from S3.
import json
import boto3
def lambda_handler(event, context):
bucket = event['Records'][0]['s3']['bucket']['name']
key = event['Records'][0]['s3']['object']['key']
s3 = boto3.resource('s3')
file_object = s3_resource.Object(bucket, key)
json_content = json.loads(file_object.get()['Body'].read())
i am trying to send the file below '105.8k' to my energy meter.
i am using the xmodem example from pypi but i get the following error:
Traceback (most recent call last):

char = self.getc(1)
File "C:\py\mainpy.py", line 62, in getc
return ser.read(size) or None
AttributeError: 'str' object has no attribute 'read'
the code i use:
### send file to port###
ser = serialPortCombobox.get().split(" ")[0]
def getc(size, timeout=1):
return ser.read(size) or None
def putc(data, timeout=1):
return ser.write(data)
modem = XMODEM(getc, putc)
f = open('105.8k', 'rb')
status = modem.send(f, retry=3)
ser.close()
stream.close()
thank you for your help.
I try to use gevent.socketio with my TurboGears 2 Website:

when i try to access the controller in the Webbrowser:
#expose('wago.templates.test')
def index(self):
socketio_manage(request.environ, {"/stat": StatNamespace}, request=request)
return dict()

I used several tutorials for pyramid to introduce myself to gevent-socketio.
I tried it with older versions from TurboGears2, gevent and gevent-socketio, i also tried this module but always the same error.
i'm pretty new to sockets, so maybe i'm just missing something obvious
the gevent-socketio recognizes socket requests only from a specific url (socket.io/1/)
because TurboGears uses the python function names as url it is not posible to us "." or "1" on the regular way. A simple solution:
#expose()
def _default(self, *args):
args = list(args)
if "socketio" in request.environ:
#do socketio stuff...
else:
abort(404)
