We have made all attribute once again. Now we have started to list about 100 color-variable products once again. But there are still two problems:

– After adding new variable products, we have to change the slug of the attribute. then the swatch color will be shown on the shop page and product page. https://nimb.ws/pCBORc. So, as you see each time we add some new letters at the end of the slug.

– During 2 days, our shop was down 5 times. (upstream time out (110: Connection time out) while reading response header from upstream). Each time after restarting the server it will run again. https://nimb.ws/aST4d3
Note: We have 4 domains on the server. When our shop is down, the 3 other one are available normal. It means the problem domain is only (brainbowtoys.de).
We talked with our server provider. After investigation, they said that by the server everything is OK. and it is happening due to some scrip in the header of the site or something like this.
I have to mention that this problem occurred during these days and before that never.

I ask you so kindly, please help me to solve these issues. We have to pay for 2 staff otherwise We have lost this week totally.

We are looking forward to your kindly effective assist to solve the issue.
