Can you also create a Docker-image for this great tool?

Describe the bug
Urls like "https://test.com/" break the entire website

Expected behavior
Should check the website like every other url

Additional context
Check of regex error, if backslash on end is allowed.

Describe the bug
After setup or if you create a new database file (site.db), the application won't work.

To Reproduce
Steps to reproduce the behavior:

1. Setup project or regenerate site.db file
2. Run application
3. Open website and see the error

Expected behavior
Index page should display without any checked websites

Additional context
The solution to this problem is already known.
The main route queries trough the database without checking if there is something in the database.
A simple check for the case of an empty table would solve this problem.

Describe the bug
After login, the navigation bar stays the same on the main page ''monitor.inspiredprogrammer.com/"

To Reproduce
Steps to reproduce the behavior:

1. Login to account
2. Go on index page (monitor.inspiredprogrammer.com/)
3. Look at navigation bar
4. Top right, login and registrer buttons didn't changed to profile picture

Expected behavior
You should see your profile picture after login.

Additional context
On any other page, you can see your profile picture on the top right.
Bug appeared after adding PWA functionality.
Have to look for routes.

Describe the bug
If try to check some urls got a Internal service error (500)
Following deeper in code I found that cause in

requests.exceptions.SSLError

To Reproduce
Steps to reproduce the behavior:

1. Paste 'https://www.old.reddit.com' to textbox

2. Click on 'Check'

3. If enabled Debug in run.py, can catch exception via console:
   requests.head(url, timeout=2, stream=True, allow_redirects=True)

4. See error

File "/Users/trx/.virtualenvs/servermon/lib/python3.7/site-packages/requests/adapters.py", line 514, in send raise SSLError(e, request=request)

requests.exceptions.SSLError: HTTPSConnectionPool(host='www.old.reddit.com', port=443): Max retries exceeded with url: / (Caused by SSLError(SSLCertVerificationError("hostname 'www.old.reddit.com' doesn't match either of '*.reddit.com', 'reddit.com', '*.redditmedia.com', 'redditmedia.com', '*.redd.it', 'redd.it', 'www.redditstatic.com', 'i.reddituploads.com', '*.thumbs.redditmedia.com', 'www.redditinc.com', 'redditinc.com'")))
`

Expected behavior
Should show real status, maybe better add a warning about SSL, or ignore it

Desktop (please complete the following information):

• OS: Mac OS X Mojave
• Browser Firefox
• Version 69.0

Additional context
Need wrap exception or do workaround. I'm don't sure what is better. Should programm check SSL or not?
Possible ignore it:
https://stackoverflow.com/questions/10667960/python-requests-throwing-sslerror

Example:
requests.get('https://kennethreitz.com', verify=False)

PS: I can take to work this issue after your decide what need to do with this error

1. Responses of last checked website and recently checked websites doesn't match
2. Response text is cut off
