Testing Cloudflare. Created WEB site, tested fine.
Went to Traffic / Load Balancing. Activated load balancing, paid $5.00. Went through the wizard, cannot save as I am getting the popup at the bottom of the page which disappears almost momentarily. It states approximately this, “Invalid load balancer name: only ADCII letters, digits, and ‘_-.’ are allowed in name: validation failed (Code: 1002)” Saving as draft fails with the same message. Nothing in the documentation or on the forum. Tried changing all names I was able to find, still negative.
The Cloudflare document https://developers.cloudflare.com/load-balancing/get-started/quickstart/ contains 14 instances of word “name”, but none of them refer to the Load Balancer name.
You’d want to enter a name like blog.example.com and then follow the rest of the wizard prompts. This doc walks through the steps, Manage load balancers · Cloudflare Load Balancing docs, that may help to visualize/anticipate these steps once you enter the hostname
This is the document referenced in this thread, post #5. Unfortunately it did not help me.
I hope my comments will be passed to the respective development team. In the worst case this thread could help somebody stumbling into the same blocks in the future.
