Hi @helongwen ,

• This is a network problem that you may need identify it yourself. e.g. Have you set the dst Harbor external url properly? Could you manually pushing image to target Harbor OR adjust your timeout settings for proxy etc..
• Harbor v2.3.4 is out of support. please upgrade to the latest ones.
