    Hi,

    Since two days ago all worked fine. But now when I do a backup it does not store it into google drive anymore. The backups end after some retries but end up in the state of “not finished”. I wonder if other have same problem?

    Any advice is much appreciated! Thanks & Cheers, Steffen

    Here is part of the log file:

    Hi Steffen,

    Can you provide the full log file using a service like PasteBin.
    There are other details which can help us identify the issue.

    Best regards,

    Hi Nick,

    Thanks for looking into it.

    https://pastebin.com/X1H5c4xy

    is the curl.php that you use out of date, perhaps?

    I had also contacted my hosting provider about the issue and also lowered chunk sizes to 25MB only.

    Here is their response:

    —

    We have thoroughly checked the server:
    Outbound HTTPS (TCP port 443) is functioning normally.
    There are no firewall rules blocking outbound traffic.
    No DROP or REJECT events are recorded for port 443.
    Connections to Google over HTTPS work from the server.

    The UpdraftPlus error is related to intermittent connection refusals from specific Google API IP addresses (http://www.googleapis.com
    ). This indicates that the issue is not caused by our firewall configuration.

    Hi Steffen,

    Thank you, I’m happy to help.

    I ran some tests with Google Drive and I didn’t experience any similar issues.
    It’s curious as initially the upload starts but shortly after this the errors kick in.

    The hosting input is useful as it confirms exactly what I see in the backup log.
    There’s a refusal from the Google API which sticks after the first instance of it.

    My suggestion at this point would be disconnect and reconnect Google Drive.
    This will confirm the authentication is valid and then you can run a test backup.

    I’m hoping it’s as simple as this, an authentication error, it’s happened before.
    If when you run the test backup the issue does persist please update me here.

    Your server looks to have enough resource to do bigger chunks than 25MB.
    Lowering it for trouble shooting makes sense, you can raise it back up later.

    At this point I think it’s more an issue of an unreliable Google Drive connect.
    The performance of the server looks to be perfectly OK with no issues there.

    Best regards,

    Nick

    Hi Nick,

    I disconnected and reconnected to Google Drive twice, also with different Google accounts, still lowered chunk sizes to 25MB. However, all lead to the same result:

    0068.100 (0) Google Drive: id_from_path failure: exception (UDP_Google_IO_Exception): Failed to connect to http://www.googleapis.com port 443: Connection refused (line: 117, file: /home/joydental/public_html/wp-content/plugins/updraftplus/includes/Google/IO/Curl.php)

    I also noticed that when I do the connection to google, then the “complete button” does not lead me back to the updraft settings page. Instead, I get an 404 error. The URL is https://joydent.co.kr/wp-admin/options-general.php?action=updraftmethod-googledrive-auth&state=success%3As-cb8154fb67c7286e632fcceb7e380f61&access_token=eWEyOS5hMEFUa29DYzZIcExjYUl4TUgwdkt0emZPakZwTlBSZ0JtX3RKYUdnSjZuMzgwbld5MkYzb2huaE4yR3k4eEZzLW5UQnExcU8tY2dITUtPSFBvbnpXWHpJWTNjN09DQ3dZU05pSmVCSHA3d3hnbEgxQWRYeXNFXzZyYnBOVWJFXzBGY2VyWXB2bEFRbnFGQ3p4UEJIcXRrS0F1X2tKSW93T3psN2t2OW9Qd1YteHBkNkZ2V01zVnFKWmhraEdoN0Zfb2ZhLVlDdU1hQ2dZS0FjOFNBUlVTRlFIR1gyTWk3cUJJdWp5Mm5kWldWakUzX2thamtBMDIwNg%3D%3D&user_id=MTI2NjExOTNjNWY3NDJiMjNjMmMyOGQ5MDdlZjZkZGQ3ZWZlMjk3YjAxMmJkNmI4MDA0YWRiZGVlYThkMDA5NA%3D%3D&scope=drive.file+userinfo.profile

    O proceed then with the manual copying of the token…

    Is your curl.php file (from 2014) perhaps out of date and is missing anything new?

    I have otherwise no problems with my google drive at all…

    Any other idea, please? Thanks for your help!

    Cheers,

    Steffen

    Hi Steffen,

    Thank you for the update, apologies for the delay over the weekend.

    I’ve been testing Google Drive this morning and experienced no problems at all.
    The reason I don’t suspect a curl version issue at this point is due to the info here:

    0084.047 (0) Googledrive chunked upload: 23.7 % uploaded (1048576)
    0099.108 (0) Googledrive chunked upload: 47.4 % uploaded (2097152)
    0114.182 (0) Googledrive chunked upload: 71.1 % uploaded (3145728)
    0129.324 (0) Googledrive chunked upload: 94.8 % uploaded (4194304)
    0140.860 (0) Google Drive: ERROR: upload exception (UDP_Google_IO_Exception): Failed to connect to http://www.googleapis.com port 443: Connection refused (line: 117, file: /home/joydental/public_html/wp-content/plugins/updraftplus/includes/Google/IO/Curl.php)

    As you can see, the connection is made and the files are being uploaded normally.
    However, after this point the connection is abruptly refused by the Google Drive.

    The only explanation I can think of for this currently is based on past experience.
    Google sometimes flag files and can erroneously block these files as suspicious.

    We’ve confirmed I can use Google Drive and there are no other reports of issues.
    Your hosting has confirmed no firewall problem, this aligns with evidence so far.

    At the moment all indications are this is an issue with Google Drive connectivity.
    It looks like you’ll need to find out why the connection is being refused by them.

    If you can upload backups of other sites to Google Drive this may be indicative.
    By this I mean it may indicate the specific contents of the backup are a problem.

    Best regards,

    Nick
