Hi all,
Link formatting
I apologize for the weird link formatting. It seems like CF won’t let me post links because I’m new to the forum.
Background
I’m chiefly a front-end developer and maintain my company’s Shopif y Plus store. Our domain is pssl.com.
User story
I wrote a Worker and created a production and staging version of it. I’d like to eventually host them at api.example.com/klaviyo/production/* and api.example.com/klaviyo/staging/*, mostly to add some CF firewall rules to these routes.
Problem
Whenever I hit anywhere within *api.pssl.com*, I receive ERR_TOO_MANY_REDIRECTS.
Steps taken so far
Worker Custom Domains developers.cloudflare.com/workers/platform/triggers/custom-domains/ and Routes developers.cloudflare.com/workers/platform/triggers/routes/ seemed exactly what I was looking for.
After following the documentation to set up the staging environment first, this means I now have the following DNS record:
+--------+--------------+----------------------+--------------+------+
| Type | Name | Content | Proxy Status | TTL |
+--------+--------------+----------------------+--------------+------+
| Worker | api.pssl.com | klaviyoproxy-staging | Proxied | Auto |
+--------+--------------+----------------------+--------------+------+
More accessible list version of the plain text table above:
- Type
- Worker
- Name
api.pssl.com
- Content
- klaviyoproxy-staging
- Proxy Status
- Proxied
- TTL
- Auto
I set the route api.pssl.com/klaviyo/staging/* on the klaviyoproxy-staging worker.
I understand this config is not what I described in my user story. But during my troubleshooting, I’ve tried all manner of Custom Domain and Route configurations just to be able to access the worker anywhere on api.pssl.com*. But I’ve always just gotten ERR_TOO_MANY_REDIRECTS instead.
I’ve searched the web for solutions. The more notable resources I came across are:
- ERR_TOO_MANY_REDIRECT S · Cloudflare SSL/TLS docs
developers.cloudflare.com/ssl/troubleshooting/too-many-redirects/ - Community Tip - Fixing ERR TOO MANY REDIRECT S
community.cloudflare.com/t/community-tip-fixing-err-too-many-redirects/42335 - Subdomain fetch causing redirect loop
/t/subdomain-fetch-causing-redirect-loop/163817
I’ve tried all the troubleshooting steps in these that I can confidently perform.
But, because this seems to be an SSL issue, I’m concerned about how changing CF SSL settings will interact with the SSL that Shopif y provides domains connected to a store help.shopify.com/en/manual/domains/managing-domains/secure-connections#acquiring-a-tls-certificate as well as all the other dozens of DNS records we have attached to this domain. You must use the TLS certificate provided by Shopif y for the store. SSL is turned off for pssl.com in CF.
Any help or guidance on diagnosing and solving this issue would be very much appreciated!
