SSRS 2022 is working on https but not on http (503)

Shahzeena 0

Hi Team, I have ssrs installed on standalone aws instance, i have https working for /Reports and /ReportServer both but http doesnt work, it starts working but then it stops i didnt change anything.

EC2 instance is a standalone server with no internet/IIS so both the request are handled by HTTP.sys.

If i enable Negotiate and NTLM both it doesnt work on /ReportServer but works on /Reports so i disabled Negotiate and now atleast both works on https,
I have removed URLRoot so SSRS can decide according to request.

I m not sure what could be the issue as it keeps giving me 503 and logs/Windows events doesnt give any information related to it.

Please help.

Hi @Shahzeena,

Thank you for reaching out on the SQL forum.

It looks like your issue is with the HTTP bindings in HTTP.sys rather than SSRS itself. A 503 from /ReportServer usually means the request isn’t reaching the SSRS service correctly.

A few things to check:

Verify URL reservations in HTTP.sys Run:

powershell

netsh http show urlacl

Make sure you see entries for both:

http://+:80/Reports

http://+:80/ReportServer If they’re missing, add them with:

powershell

netsh http add urlacl url=http://+:80/Reports user=DOMAIN\SSRSAccount

netsh http add urlacl url=http://+:80/ReportServer user=DOMAIN\SSRSAccount

Check SSRS config In RSReportServer.config, confirm <UrlReservations> includes HTTP as well as HTTPS. Since you removed UrlRoot, SSRS will auto‑detect, but it still needs valid reservations.

Authentication settings If Kerberos isn’t configured, disable Negotiate and leave NTLM only. /Reports can fall back gracefully, but /ReportServer often fails if Kerberos tickets aren’t available.

Firewall and security groups Double‑check that port 80 is open in both Windows Firewall and your AWS security group.

Event logs Look under System → HTTP Service in Event Viewer. HTTP.sys errors often show up there, not in SSRS logs.

Hi,

The URLACL was not listening for 443 and 80 both though we have registered everything from SSRS Configuration manager and through Powershell, i had to restart http.sys and after many attempt it took my input and started listening , but still it was giving me http protocol error page then i restarted server and it took all the config and it started working,

All the config you mentioned is very well in place its nothing which was causing issue.
I tried removing negotiate and only using ntlm but this wasnt any issue, currently i have both enabled still the solution works.

My concern is why it does not register url through the command , configuration manager and even through config, is it common that it just doesnt give any error and does not register also.

It was causing so much trouble as logs gives no error, i know for a fact http.sys works at kernel level so we will not have it in application logs.

Main concern was http.sys was not at all registering my url at 443 and 80.

After registration why i had to restart http.sys and whole server, this doesnt seem right to me.

Thanks.
