[twofaktor]

Describe the problem/bug
When I set the .env.local file setting FETCH_FEES = false and I customize the MEMPOOL_URL= to use another URL, I can see the next on logs when I logged in:

Also, on ThunderHub, you can see the fees section when it shouldn't appear

Your environment

• Version of ThunderHub: v0.13.24 Latest
• Deployment method: npm install
• Other relevant environment details:
  • Ubuntu Server 22.04.3
  • Node v20.10.0
  • NPM: 10.2.3

To Reproduce
Steps to reproduce the behavior:

1. Set FETCH_FEES = false and I customize the MEMPOOL_URL= to use another URL on .env.local
2. Start ThunderHub
3. Go to the default URL:PORT
4. Login with your account
5. You can see the fees section has been loaded and on ThunderHub logs a message Problem getting Bitcoin fees

Expected behavior
FETCH_FEES = false should act and not show the fees section and nothing related to fees on ThunderHub outputs

Actual behavior
Fees section + error Problem getting Bitcoin fees
