Check the panel to cloud server network is unstable
Try to click the fix button on a machine that cannot be updated. The fix and update effects are the same.

Can I check it in your panel? If you allow, please send the account password and login url to zhwyeah@gmail.com, thank you
If not, you can use the install command to overwrite the installation of the panel once, you can achieve an upgrade.
aaPanel_Jose Account Sent to your email Jose,.. Thanks anyway,.

The network is unstable. . . It may be normal after a while, if you ping www.bt.cn on the serve has response indicating that the network is normal.
