# Frequently Asked Questions

Q: How can I refresh a comment/subreddit/submission?

A: Directly calling the constructors will refresh the value:

    reddit.comment(id=comment.id)
    reddit.subreddit(display_name=subreddit.display_name)
    reddit.submission(id=submission.id)

Q: Whenever I try to do anything, I get an `invalid_grant` error. What is the cause?

A: This means that either you provided the wrong password and/or the account you are trying to sign in with has 2FA enabled, and as such, either needs a 2FA token or a refresh token to sign in. A refresh token is preferred, because then you will not need to enter a 2FA token in order to sign in, and the session will last for longer than an hour. Refer to Two-Factor Authentication and Obtaining a Refresh Token in order to use the respective auth methods.

Q: Some options (like getting moderator logs from r/mod) keep on timing out. How can I extend the timeout?

A: Set the timeout config option or initialize `Reddit` with a timeout of your choosing.

Q: Help, I keep on getting redirected to `/r/subreddit/login/`!

Q2: I keep on getting this exception:

    prawcore.exceptions.Redirect: Redirect to /r/subreddit/login/ (You may be trying to perform a non-read-only action via a read-only instance.)

A: PRAW is most likely in read-only mode. This normally occurs when PRAW is authenticated without a username and password or a refresh token. In order to perform this action, the Reddit instance needs to be authenticated. See OAuth Configuration Options to see the available authentication methods.

Q: Help, searching for URLs keeps on redirecting me to `/submit`!

Q2: I keep on getting this exception: `prawcore.exceptions.Redirect: Redirect to /submit`

A: Reddit redirects URL searches to the submit page of the URL. To search for the URL, prefix `url:` to the url and surround the url in quotation marks.

For example, the code block:

    reddit.subreddit('all').search('https://google.com')

Will become this code block:

    reddit.subreddit('all').search('url:"https://google.com"')
