WebSocket time error

[XiaoPeng0x3]

I follow the doc and deployed overleaf on my server. As in the documentation, I have created an administrator account. However, the problem shown in the following picture emerged.

I can still use the functions of overleaf normally. This issue seems to have no impact. Can I just ignore it?

My problem is caused by the proxy setting in the configuration. Refer to this #354 (comment)
