Grok Matches but getting _grokparsefailure in Kibana

Elastic Stack Logstash
1

I don't know what's wrong here. Grok matches for access.log but when creating index pattern in KIBANA logs showing _grokparsefailure
I'm using ELK version of 6.5.4.

Sample log -

157.50.50.50 - - [28/Mar/2020:13:36:28 +0530] "GET /my/v1/acc/card?density=XHDPI HTTP/1.1" 200 541 "-" "-" "okhttp/3.12.1"rt=0.056 uct="0.000" uht="0.055" urt="0.055" uaddr="10.22.33.44:8080"

I created 3 groks all are matching but none are working. conf file & 3 groks are below -

filter {
  if "access" in [log_type] {
  grok {

	match => { "message" => "(?:%{IP:clientip1}|-) (?:%{IP:clientip2}|-) (?:%{IP:clientip3}|-) \[%{HTTPDATE:timelog}\] \"%{WORD:verb} %{URIPATH:request}?(?:%{URIPARAM:url_querystring})? HTTP/%{NUMBER:httpversion}\" %{NUMBER:response} (?:%{NUMBER:bytes}|-) (?:%{DATA:blank1}|-) (?:%{DATA:blank2}|-) %{DATA:agent}rt\=%{NUMBER:rt} uct\=\"%{DATA:uct}\" uht\=\"%{DATA:uht}\" urt\=\"%{DATA:urt}\" uaddr\=\"%{DATA:uaddr}\""  }	

#	match => { "message" => "(?:%{IP:clientip1}|-) (?:%{IP:clientip2}|-) (?:%{IP:clientip3}|-) \[%{HTTPDATE:timelog}\] \"%{WORD:verb} %{URIPATH:request}?(?:%{URIPARAM:url_querystring})? HTTP/%{NUMBER:httpversion}\" %{NUMBER:response} (?:%{NUMBER:bytes}|-) (?:\"(?:%{URI:referrer}|-)\"|%{DATA:referrer}) %{DATA:agent}rt\=%{NUMBER:rt} uct\=\"%{DATA:uct}\" uht\=\"%{DATA:uht}\" urt\=\"%{DATA:urt}\" uaddr\=\"%{DATA:uaddr}\"" }	

#	match => { "message" => "(?:%{IP:clientip1}|-) (?:%{IP:clientip2}|-) (?:%{IP:clientip3}|-) \[%{HTTPDATE:timelog}\] \"%{WORD:verb} %{URIPATH:request}?(?:%{URIPARAM:url_querystring})?

 	 }
  }
}

output {
  if "access" in [log_type] {
    elasticsearch {
      hosts => ["10.5.10.5:9200"]
      index => "<gg-check-{now/d}>"
    }
  }
}

Please help & suggest. Thanks in advance.
