403 from a fetch request from a Worker

Wrangler

Workers

Hello, I use Hono for my Worker and there I have a specific endpoint, where I basically proxy a request from one of the delivery company in my country to my users to see their available office locations.
My issue with it is that I get error "403 - Your connection is using an outdated security protocol. Please upgrade your browser." when I call their public API. I got in touch with the company, but they told me that everything is okay from their side, so I believe the issue is in my network setup of the Worker. This is my endpoint code:

const SPEEDY_API_BASE_URL = 'https://api.speedy.bg/v1';
const speedyUser = await c.env.SPEEDY_USER.get();
const speedyPass = await c.env.SPEEDY_PASS.get();
const requestBody: SpeedyFindOfficeRequest = {
  userName: speedyUser,
  password: speedyPass,
  language: 'BG',
  countryId: 100, // Bulgaria
};
const response = await fetch(`${SPEEDY_API_BASE_URL}/location/office`, {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
  },
  body: JSON.stringify(requestBody)
});

const SPEEDY_API_BASE_URL = 'https://api.speedy.bg/v1';
const speedyUser = await c.env.SPEEDY_USER.get();
const speedyPass = await c.env.SPEEDY_PASS.get();
const requestBody: SpeedyFindOfficeRequest = {
  userName: speedyUser,
  password: speedyPass,
  language: 'BG',
  countryId: 100, // Bulgaria
};
const response = await fetch(`${SPEEDY_API_BASE_URL}/location/office`, {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
  },
  body: JSON.stringify(requestBody)
});

Also this is the beginning of my

"workers_dev": false,

It is good to mention, that when I run my worker locally it works. If someone has an idea how I could resolve this issue it would be great.
