svn: PROPFIND request failed on 403 forbidden error - Tortoise SVN

At instances when we try to update our source code from CMD prompt or PUTTY using the following command in Tortoise SVN,

# svn update
or
# svn up

We may come across the following error

svn: PROPFIND request failed on '/svn/repos/yourfolder'
svn: PROPFIND of '/svn/repos/yourfolder': 403 Forbidden (https://yourdomainname.com

The solution for this error is:

svn update --username your_user_name

where,
'your_user_name' is your SVN user name

Once you type this command it ask your password

Authentication realm:
Authorization Realm Password for 'your_user_name':

After this type your password. This will resolve this problem and your source code will get updated.

If not please try some other procedures.
